This is the craziest A cappella performance ive ever heard. To be able to make those sounds and a song like this without instruments is insane.

"They're making me have involuntary body functions!" Yep. That's Pentatonix!!

the guy you referred to as Michael is Mitch. And yeah, he has a 6 octave range. Watch Aha Live Singapore. it's a video from one of their concerts where Mitch goes off with the high notes, and Avi breaks the sound system with his low notes.

That look of surprise upon realizing that Mitch can go high... It's called "Mitch face" and all Pentaholics live to see it on newbies!😅 Welcome to the rabbit hole!!

"Involuntary bodily functions", never heard it called that, but addiction can do strange things, and they are an addiction. Avi Kaplan, bass singer, is an opera trained basso profundo, so the depth of his voice and the quality are extreme. Mitch does have a huge range, from mid-baritone to high tenor (also can do whistle tones). Kirstie can sing just a few notes higher than Mitch, and they harmonize amazingly together. Scott can go from mid-range bass to tenor, and has a strong falsetto. And Kevin, while being a beast at beat-boxing, can play cello, sax and keyboards - AND he has a great tenor voice. The trio (Scott, Mitch & Kirstie) met as kids in local musical productions and sang together in high school. In 2011, they asked Avi and Kevin to join them to go on a TV competition show The Sing Off, which PTX won, even though they had just met! Anyway, we, the Pentaholics welcome you to our fate.

"Causing me to have involuntary bodily functions" You are NOT alone!!!! There are hospital wards devoted solely to Pentatonix-listeners.

All of us PTX fans don’t care if you pause the song 10 times, we listen to all their songs 100 times plus we watch as much reaction channels as we can. We are just here for your reaction and seeing people who haven’t heard of their group react to their music for the first time so don’t worry about talking over the song and pausing, it’s all good

My favorite detail is in the build to the last drop, Kevin is using an extra punch of breath that actually adds a vocal weight to the beats. I love it so much!

The bass and "that drop" is Avi Kaplan. He is ultra talented. (not ashamed to say he's my favorite lol) He also helps Kevin. If you watch him he does wind sounds, synthesizer sounds, he can do overtones and coupled with Kevin's crazy skills they are unmatched in my opinion. The two of them also wrote this original song. They were best buds and roommates. I also especially enjoy Mitch and Avi together because of the contradiction in their tones. Avi and Kevin support the foundation but Avi Supporting Mitch's voice is heavenly to me. Avi also has a crazy range and you will witness that in other videos. Scott's voice is like honey and his riffs and runs amazing. Mitch is sassy and sings those high notes without straining a thing. Cool as a cucumber. Kirstie has a very pretty tone (I believe she's mezzo soprano) and has done some Broadway. Keep up the PTX reactions. Love them and especially loved this one!!! Looking forward to Hallelujah so hope you can get that one through. Thanks.

Before you go too far down the Pentatonix rabbit hole, I'd encourage you to react to their performances on The Sing Off, the competition show that put them into the spotlight. At the time they auditioned for the show, Mitch Scott, and Kristen had been singing together for several years already but Avi (bass) and Kevin (beatbox) had literally joined the group a few days before. When recording of the show started, they'd only had about 3 months working together. They blew me away then and they still blow me away. But it's great to see those earlier performances and contrast them to what they've done since.

Best comment ever"these guys make me have involuntary bodily functions" 😆

Kevin (beat boxer) and Avi (bass) are the best rhythm section ever! They were room mates for years and would practice for hours to hone their craft. Avi often did more than bass, his swoosh sounds and drops are incredible. So together they create just magic. The trio are brilliant but I'm with you Avi & Kevin are awesome. They were named 'Meat & Potatoes" by the judges on Sing Off as they carry the main flow of transitions etc...and if you're nodding or tapping your feet it's because of them lol...ahuh I'm a huge fan lol

Guy in white hair is Scott - he really is a leader, he usually sings as the first nowadays. Also, he is making all compositions! Btw. guy singing here these high notes is Mitch He is literally insane!

Love Again, yes! Oh yeah, you're one of the Pentaholics now. And welcome to the Mitch (high range) fan club too! Dance of the Sugar Plum Fairy (it's insanely good, won them their second Grammy) has a bit where he will almost rupture your eardrums with how high he goes (and then TKO you with how low Avi drops a bass note). And for another banger, try their cover of Macklemore's Can't Hold Us. There's so much awesome to discover with this group.

Kevin can do anything.

Avi's bass has blown speakers. Also listen to some of his overtones. It explains some of the synthesized sounds you here. As to whether Mitch or Kirstin can go higher, I believe it is Kirstin, but Mitch has such amazing vocal control that even amazes the other group members.

They are like my kids and grandkids... I can’t pick a favorite! They all bring something unique to the table! :)

The one you call the lead is Scott. He has an amazing range. They all lead from time to time. It depends on the song. Scott can also do base. Usually when Avi or Matt are singing.

If you want to hear Avi's lows, a really fun example is when he sang with another group, Home Free, with the song "Ring of Fire"

The reaction to Kevin and Avi breaking out the dubstep is always amusing to watch on peoples reactions.

They are all on another level. Mitch Grassi has a 6 octave vocal range. They refer to him as a Lyric Tenor. Kirstin "Kirstie" Maldonado has a 4 octave vocal range as does Scott Hoying and Kevin (Beatboxer) Olusola . Avi Kaplan has a 5 octave vocal range.

I really like Avi's robotic moves at the end

I heard that even if it gets block as long as you dispute it, they typically release the block within a few days. Or try adding a couple of pauses with a graphic to break up the videos a little more if they get initially blocked. 👍

Oh dude you have to watch Cracked! And Havana! The Talent never ends with them! If you want lows and highs....You have to watch, Aha! Singapore @ The Star Vista! Thanks for reacting!

Wait til you hear their own composition "Run to You" very emotional.

LOVE your reactions to PENTONIX! 🤣 KEEP EM COMING!

To answer a couple of your questions - all of the members contribute to the 'music' in various songs. You noticed it in Daft Punk when you asked about the keys - that was Mitch and Kirstin at (they were humming closed-mouth so you thought they were bobbing lol). Kevin is almost always on beatbox, though he sometimes adds some vocals (especially noticable in this song in the opening). Avi does sometimes help out with the beatboxing, but he usually sticks to bass afaik. Avi and Kevin usually trade off on the 'other' noises (wind/whooshing effects, etc.) Avi also does overtone singing, which you will hear sometimes and contributes a really cool effect when it's used. Kirstie can go higher than Mitch (and he goes lower than her, at least from what we've heard of them), but they both occupy a similar range and they can do amazing harmonies together. They used Mitch for a lot of the highs in their earlier stuff, and there's a bunch of theories as to why - Kirstin was less secure about her voice, or that her voice was more fragile on tours are the two I see most often. Recently, Mitch has said he's tired of just doing high notes (and they were doing 2 tours a year for 2 years in a row so it was probably wearing on him), and Kirstie also had a stint on Broadway that raised her confidence greatly, and she's been taking more of the high notes as of late. Her highs are lovely and her mid range is absolutely gorgeous. She can also do whistle notes (people say Mitch can, but he's the first to admit that he doesn't actually do it because the technique he uses is an inhaled squeak) It's easy to point to Mitch's high notes as his cool factor, but really for me the coolest thing about his singing has always been his control. He's absolutely nuts in that regard and he can just run all over his registers. He's also apparently the most consistent singer live. Scott (blond guy) has the largest general singing range in the group (unless you're counting Mitch's inhaled squeaks, which I don't because it's unlikely he'll ever use those in a song and also whistle notes are just a different technique all together and can be done irregardless of range) - he covers bass when the bass singer is singing (you would have heard it in Hallelujah when Avi was singing) and he can go very high in his falsettos (not sure what the best example song would be). Scott is also known for his riffs and runs, and he really shines on R&B songs imho, but he has the most versatile voice in the group. Kevin is beyond talented - on top of his beatboxing, he's an incredible cellist who's played at Carnegie Hall (and he plays like 4 other instruments). Scott found him on KZfaq doing 'celloboxing' (playing cello while beatboxing), and PTX does some songs with cello were Kevin celloboxes. He also sings, and he has a lovely tenor (and he can go as high as Mitch - they sometimes argue in interviews/PTXperience about who goes higher, they each say it's the other). He has his own channel where he does looping covers, with various instruments, loop pedals, beatboxing, and singing. It's absolutely cool to check out. He also has perfect pitch Avi as you know has some crazy lows, but his singing voice is also beautiful. He also can do overtone singing, as I mentioned earlier. After leaving the group he's made some solo music which is gorgeous, definitely worth a look. Matt (who replaced Avi, you would have seen him on the Sound of Silence) doesn't go as low as Avi, but has a tone much more similar to Scott's and PTX has been playing with their sound together a bit. He's also got a wonderful singing voice, and it looks like Scott is more comfortable taking bass (either just in general, or from Matt) so we're getting to hear him in lead parts quite a bit which is very nice to hear. I think one of the great tragedies of Avi's time with PTX was how infrequently he got to take lead parts, for such a gorgeous voice Wow this turned very long haha. And my two fave voices got the shortest bits lmaoo

You should look at the pentatonx cover of „come along“🤩

Glad you got this one up. I laughed out loud a few times. Thanks for that. Keep the PTX coming and we Pentahoilcs will be here for it!

I'm surprised you are shocked by his range, given you already watched HALLELUJAH. He hits the stratosphere on that one.

Thank you for reacting to this Pentatonix original. I love it. I never understood the need to pick and voice a favorite out of a group. They are all amazing. I don't get the point. They have some great originals. I hope that you react to more of them. They will release a new album of original songs on 2-12-21.

LOL I snorted when you snotted. Hahaha Suggestions: La La Latch New Rules x Are You That Somebody Say Something Shallow Rather Be Can’t Hold Us Can’t Sleep Love Run To You Cracked ...and ANY one of their evolution videos, which are all amazing. I just subbed, you make me laugh.

Avi's got some amaaaazing solo stuff, you should definitely check them out! Some of my favorites are: Aberdeen, Sweet Adeline, Sweet Adeline pt 2, Otherside, and I'll Get By.

I hope you've disputed the blocks to your Bohemian Rhapsody and Hallelujah reactions so we can hopefully eventually listen to them! You should react to their Live Popspring 2016 performance. It has three original songs (Cracked, Can't Sleep Love, and Water), plus their Evolution of Michael Jackson (which is epic!) You aren't as likely to get blocked for their live stuff, and this Popspring video is especially good because it was officially filmed by MTV, so the quality is class. Other videos you aren't likely to get blocked for are their Evolution of XX (insert artist here) videos and Gold (really any of their YT videos where there isn't an album/EP equivalent song their record label can sell). Keep going with PTX!!!

They're making me do involuntary bodily functions! Priceless.

I think Scott (tall blond baritone) is naturally the most extraverted. But in live performances, you can also see him smiling proudly at his old schoolmates Mitch and Kirstie when they do great on solos. Yes, on songs like this they all do instrumental effects. Avi does the epic bass slides, and he can do overtone singing (where he does 2 notes at once). Kevin can do just about any percussion, but Avi often does the bass drum.

Mitch’s highs and Avi’s lows = utter perfection. I absolutely adore Avi, but Kevin, Kirstin and Scott are also insanely talented, and show it in other videos. If you haven’t already seen it, you should check out Dance of the Sugar Plum Fairy - where they are literally the instruments x

I’m so bummed that your reaction to “Bohemian Rhapsody” got blocked!! I was really looking forward to that one! I hope you can dispute it. You should definitely check out their cover of Macklemore and Ryan Lewis “Can’t Hold Us” and their “Evolution of Michael Jackson”. They also have another original song called “Sing” that is absolutely ridiculously awesome.

This song... Yes, Avi, teach me.

This is an original Mitch is a counter tenor, he can sing just slightly higher than Kirsten

Absolutely yes with the Patron page!

Loved the melt to the floor, haha!

Another reactor mentioned putting in a dispute to KZfaq and their video was released within 48 hours. Said they often have to with Pentatonix videos. Wouldn't hurt to try.

did you notice Scott's thumb when he said "Work" it was a play Icon on his thumbnail.

Avi and Kevin are beasts. I have no specific recommendations because anything from them is amazing.. I especially love everything from the time Avi was with them still.

His name is Mitch. Listen to Defying Gravity by Superfruit. His high range is awsome!

Wait till you hear kevin sing I suggest imagine or amazing grace he sings in both of em. Or you could check out Kevin's solo work.

Avi is bass, Scott is baritone, Mitch is tenor, Kirsten is soprano, and Kevin is beatbox and plays cello!

The best thing about Mitch’s range is that he does it all effortlessly

Please react to their new album, The Lucky Ones!!! Coffee in Bed, Never Gonna Smile are my top two!!!

Mitch goes even higher in “Aha” Singapore live

They are in one word .. magnificent !

Kevin - Black guy - Beatboxer, sometimes cello too, and some tenor/high tenor on a few songs. Avi - Vertical forehead dots and great crazy eyes - Bass, very, plus up to high baritone or low tenor. Scott - Tall, white hair - Baritone and tenor with some bass. Kirstin - Goggles - Mezzo Soprano plus some extra soprano. Mitch - Dark hair, bedazzled face - tenor to very high tenor. The key trick is that their individual ranges are quite wide, so there is a lot of range overlap, so the arrangements can have really good "movement" where a higher part can slide under a lower part and vice versa. You don't really think about it, but your brain really likes the movement. Avi being bass does a lot of bass guitar part and will often follow Kevin's kick drum with a heavy bass push. They are a very tight team. I'm not sure, but I think most of the drops are a duo thing between Kevin and Avi if they have a very low component. When Avi is on a solo or otherwise busy, then Scott covers bass and does rather well, but I assume they arrange it within Scott's bass range rather than Avi's extreme bass range. Scott has often been the opening "front man" on many songs, especially the earlier ones. I suspect he just had more confidence to open at the start of their career. At this point any of them can break the ice. Mitch is a very confident singer now. Kirstin has been on Broadway (Kinky Boots). Avi now has a solo and collaboration career. I suppose Kevin isn't quite ready to open a Pentatonix song, but he does his own solo work also, so he probably could. They do a great version of Radioactive with Lindsey Stirling (violin dancer) and Kevin celloboxes! One of their fun little fantasy songs is Come Along (cover, but not well known). You'll love Mitch in that. Matt Sallee is the new bass since 2018 or so. He is a lot of fun. Try a post season Christmas song with You're A Mean One Mr. Grinch, which has a great bass lead.

👉Scott Hoying - tall blonde guy sings baritone, takes over the bass when the bass has a lead. Hits siiiick falsettos, KING of riffs and runs VERY SOULFUL!! 👉Kirstie (Kirstin) Maldonado- mezzo soprano, Alto 👉Mitch Grassi - counter tenor 👉Kevin Olusula (K.O) - beat boxer, tenor, cello 👉Avi Kaplan - bass / basso profundo, baritone, overtone ......👉Matt Sallee (replaced Avi in late 2017) bass, baritone.

This song features Mitch. For Kirsty being featured, check out "Be My Eyes". As I understand it, Scott does most of the arranging. To get the full spectrum of their abilities, you need to listen to multiple songs as they tend to rotate through the group. Matt, the new guy, gets featured in Mr. Grinch. Also, check out their cover of "Radioactive" which they did in collaboration with Lindsey Stirling. Also, thank you for the birthday present. Jan 29.

Scott Hoying, Mitch Grassi, Kirstin Maldonado, Kevin Olusola, and Matt Sallee . and Avi

Ladies and Gentlemen, I present to you, “The Pause King”. You’re Welcome!

I love this song ❤ thank you for reacting to it 😊

Look them up and add their names to your Google doc sheet with their music. Scott (light hair baritone most leads). Mitch (very high range with normal tenor range). Kristen - Kristie (rhames with thirty) is a soprano. Avi (sounds like aaaavvvvv) amazing bass, has about a 6 active range. Kevin - the most amazing beat boxer, he also sings in a regular/tenor range. He also has a slightly higher range than Mitch when he want to. Matt - newest bass singer, Avi helped pick him for the group before he left in 2017, he also has an amazing range. Hope this helps you out.

Don't box yourself in and feel like you have to commit yourself to a favorite...it will never work! 🤣🤣 Fav's will change from song to song because they're all so talented & versatile.

"Involuntary body functions" LOL. Refreshing reaction - stops and commentary genuine. (Snot on my brutha)

Also, this is probably on your list but “Aha!” Live from the Star vista in Singapore should be on there! Fan shot footage from a concert, it’s sooo good

Kevin is a spectacularly talented human being. Try his solo stuff. His name is Kevin Olusola / K.O.

Lol. Loved your reaction when you got "Mitch slapped". ♥️

FYI, anything before 2015 from Pentatonix does not need breaks because they were with a different record company or not with one at all. After they switched to major label RCA, RCA has been cracking down on youtubers

That was a fun reaction 😁😁😁 Looking forward to more 👍

Yes, second from the right is Avi. He was replaced by Matt when he left the group. He is the base.

It is an Original. Listen to Gold (a cover), and Dance of the Sugar Plum Fairy (their 2nd Grammy). Then, can you listen to some of Avi Kaplan's solo stuff please. He left PTX around Sept 2017 (although it was announced in June or July 2017). Very different music, but maybe you'd like Change on the Rise. New here. Thanks!

Bro there’s a private performance of this for a tv show where they all just stand there and perform this song for like two people... it’s incredible.. Kevin even nails this part 7:08 👌🔥

Love your reactions! Fun to watch!

There's a thing some singers can do where they produce an absolutely pure timbre - if they can put enough vocal power behind it and hold a note exactly for a few seconds, they can break things if their pitch matches the frequency of those things. In PTX, both Mitch and Avi have broken speakers when the sound guy forgot and left the amps up too high. Kirsten and Mitch have both shattered glasses without even an amp.

You can go off on different tangents with Pentatonix side-projects. If you're into the beatboxer (Kevin Olusola), check out his "KOver" of "Down" by Marian Hill. If you're into the bass singer (Avi Kaplan), check out his solo song "Change on the Rise" or his collaboration with another a-cappella group, Home Free, covering Johnny Cash's "Ring of Fire". Mitch Grassi (unusually high male voice) and Scott Hoying (looks like the front man) have a side project called Superfruit that includes some comedy and songs where Kirsten Maldonado (female member) sometimes guests. Maybe check out Superfruit's "Guy.exe" or their "Frozen Medley". Matt Salle replaced Avi Kaplan as bass when he left amicably due to personal/family issues. He's in later videos like "Sound of Silence", "Mad World" and "My Favorite Things"

Dude, there's a beginner's guide video on pentatonix that gives you the rundown from A-Z and get you all caught up on their names. Check that out.

HAHAHAH!!!!!!!!!! "I'm mellllllting!!!!!" hahahha! Feel It Bro!!!!!!

Love your reactions! Avi does the bass drops and times his bass with Kevin's beat-boxing. Some reactors post a link to a copy of their reaction to Vimeo to bypass the copyright issue. You should check out their mashup cover called La La Latch and Havana.

Welcome to the rabbit hole...my fav song/singer/vid usually changes with my most recent viewing 🤣

There's and interview/ live green room performance of this song by 24/7 City Secrets that's incredible

I suspect that Scott often opens becuase he's right in the middle of the scale, allowing the other voices to bring the song up or down later. Also, he reputedly has a four octave range, and he can do backing in either end when it's anyone else's solo. (Eek, originally typed Matt instread of Scott.)

I just love your reactions

One thing to keep in mind is that if you follow the Fair Use rules properly then your reaction might get blocked initially but if you challenge the block it will often get lifted in about 48 hours or so. You can post up after the block is lifted. But, you have to follow the Fair Use rules for that to happen, since the initial block is just almost automatic.

I am begging you to please listen to Hallelujah. I swear, it will absolutly knock your socks off. 🙏❤️ Loved this reaction btw Beatboxer: Kevin Super bass: Avi Only girl: Kirsten (Kirsty) Dude hitting the high notes: Mitch Frontman: Scott And for future videos like Sound of Silence, Matt joins and Avi leaves

You are soooooo funny I just love your reaction at 8:31 🤣🤣🤣 this is so accurate when it comes to Avi and Kevin. New subscriber for sure.

Fun reaction! Just subbed. To answer a few of your questions. The drops were Avi, the bass. He is insanely talented, but then they all are. Mitch often sings higher than Kirstie in their performances, but every now and then Kirstie will show her range and it is impressive. I think they let Mitch have a lot of the high parts because it is more impressive coming from a guy. But I think Kirstie can go just a little higher. Both sing whistle notes effortlessly. Kirstie has a beautiful lower register, but can also sing like a Disney Princess. World class talent, like the rest of them. Scott, the blond guy, is out front more often and may have the most versatile voice, but they all get plenty of chances to take the lead. PTX is good about giving the lead to the singer whose voice suits the song best. Kevin is super human. The sounds he can make are insane. And he is a concert-quality cello player.

Meat and Potatoes astound everyone. This is my favourite song they’ve done. Great reaction. Also check out their new original album!

If you really want to hear a male with astonishingly range ( the guy can sing high notes NOT even on a piano! ) check out Dimash Kudaibergen from Kazakhstan. He sings in 12 languages, and has music degrees. I GUARANTEE YOUVE never heard a man sing like this! By all means keep on the PTX train, but definitely check out Dimash, you won’t regret it. You start reacting to him, you will have thousands of his fans ( called Dears ) joining your channel!

yeah, you've been Mitch Slapped LOL

This one is my favorite to watch reactions to. I think it's so underrated.

I laughed when I saw your thumbnail for this video and your referencing my comment of melting to the floor...that’s awesome!!!🤣👍🏼🤣👍🏼....you gotta react to Sing and Rather Be

You bin Pentatonixed, dude!

Kinda seems like the reactors that rewind several times, just to rehear good part, have less copyright issues. 🤷‍♀️

My favorite things They said it was mad hatter and steam punk if you see it youll go yea ok.

Involuntary bodily functions!!!! lolol dude that was great!! I've found that whichever is singing at that time is my fav. or beatboxing or bass dropping...ok so all of them. They are almost incomparable in their talent level. Welcome to the rabbit hole. Additionally check out Kevin and "Down"

Everyone; : "But you can't do EDM acapella." Mitch; "Hold my Red Bull"

If you want a fun one that has Avi hitting his lowest note, check out Todrick Hall's "Wizard of Ahhhs - Featuring Pentatonix". Kirsten absolutely kills it as Dorothy and both witches. It is not what you think, but I don't want to give away any surprises.

It's like I always say, Scott is my favorite, his lead Rock and Roll voice coming thru! Cept for Kevin, that on point drums! Avi is awesome, his bass voice is butt shakingly great! Mitch is unbeatable sing strong above everyone! Kirsty is the true star, when she wants she belts it out and is Unstoppable! Matts Awesome, but I get his stuff in the early days.

If you're having trouble remembering names, you could always open up a Notepad on the side of your screen with their names, and the descriptors that you remember them as. ;-) Scott - "Lead", Mitch - "Hipster", Kirsten - "Chick", Avi -"Bass", Kevin - "Beatbox". I don't personally agree with your descriptions, but I can understand your point of view. ;-p

It is an original song and, yes, they can sing it outside of a studio. Here they are in the middle of an interview in (what looks like) an abandoned diner. kzfaq.info/get/bejne/mKlph8yUvJbNmY0.html Her name is Kirstin. Pronounced Cur-stin. The bass is Avi. Pronounced ahh-vee. The tenor is Mitch. The beat boxer is Kevin. The baritone is Scott. He often sings first. He is the compulsive workaholic of the group who comes up with ideas like producing an EP while in quarantine in five different places.

And I’m sure it’s been suggested, but if you wanna be blown TRUELY away by Mitch, watch Aha! At the Star Vista in Singapore. It’s filmed on a phone (but great quality)!!

Love your reactions to Pentatonix. Yes, Mitch can sing higher than Kirsten. Love your Smoky Mts sweatshirt. I live 20 minutes from the park on what's called "the quiet side".

"Dude, they're makin me have involuntary body functions over here" HA! Love your reaction to this Kevin! 😅
