Just wait til you discover that Kevin, the beatboxer, can beatbox WHILE playing the cello (cello-boxing).

They use a drum machine. But he walks, talks, sings, and plays cello too. He's Kevin Olusola.

I'm actually pretty stunned that there is still anyone out there, especially in the music field, who has not heard of PTX yet, but I am glad that there is because it's so much fun to experience a first time listener!

Hallelujah bohemian Rhapsody sounds of silence 🔥🔥🔥🔥

Must see their Daft Punk Medley. Won a Grammy for it.

I think you'd love their 2014 Grammy-winner, Daft Punk medley. They got their start in a 2011 a capella contest show called the Sing-Off, where the three friends Scott Hoying (baritone), Kirstin Maldonado (mezzo soprano, but more alto in recent years), and Mitch Grassi (tenor/countertenor), who had sung together in as The Trio in high school, were joined by beatboxer/cellist Kevin Olusola and bass Avi Kaplan (replaced in late 2016 by Matt Sallee, whom you saw in this video - the only personnel change in 10 years). Spoiler: they won the contest. But the recording contract they were promised as part of the prize fell through because the company didn't think it could market them. They took to KZfaq and other social media platforms, making videos non-stop and then touring relentlessly. Their catalog is rich and deep, evolving from mostly covers and medleys to a number of original songs now.

They also do originals: love me when I don’t, coffee in bed, teach you how to love!

Yes they are beat boxing too. Acapella unless occasionally they have an instrument If they employ an instrument it will be visible in the video.

Welcome to Pentatonix! Thank you for your reaction. Their name comes from referring to the pentatonic scale something to do with the number 5. They were a trio, Scott the baritone (wearing the yellow jacket and funky glasses), Kirsten the only girl/woman and Mitch. He is a counter tenor which allows some really high notes as well as a lower register. They knew each other as young kids and in high school used to sing together. In Scott’s 1st year of college he heard about a TV show that would feature a capella groups. He called Kirsten and Mitch but they also needed a bass and percussion to fill out the group. The 1st bass they met and he fit right in his name is Avi and Kevin was discovered on the Internet playing the cello and beatboxing. He was contacted and agreed to be a part of the group. They only had a few days together to practice before going on the show (called the Sing Off). I believe it was the 3rd season which they won. Their videos are still on You Tube. This was back in 2011 when Scott, Kirsty and Mitch were ALL 19 years old!

Your "problem" is Mitch Grassi, an amazing counter-tenor who is always surprising/shocking new listeners who do not expect to be "Mitch-slapped."

You pronounced correctly number one Try Bohemian Rhapsody, Daft Punk, Can't Holds Us, Amazing Grace. Any of their evolutions, MJ, Rihanna, Beyonce. It's a wild ride

You are correct. Pentatonix is an acapella group and one of the best in the world with three Grammies. You may also want to watch their "Dance of the Sugarplum Fairies."

Welcome to the wonderful world of acapella groups pentatonix, home free, and voice play the big 3 all have amazing vocals amazing bases and amazing beatboxing. Welcome to the Rabbit hole! It's an amazing journey that so far is never ending!!!

Millions of records sold, 3 Grammys won, world tours. This is the premiere a cappella group in the world. They have been together 10 years with only one person change. Avi.-original base 2011-2017. Left friendly for illness in his family. Replaced by Matt 2017-now Their catalog is wide and deep. Not a bad song in the bunch. They are simply amazing

They are really the number one best acapella group out there. And I can't guarantee you won't become a pentaholic.

Yes this is all a capella, they are pretty much the Elite class in a capella. Check out Amazing Grace, Sound of Silence, Mad World, and New Rules x Are You That Somebody (just a few in my top ten)

I’m not even halfway through watching and I just subscribed. I love your energy!

I think you would really enjoy their "Evolution of Michael Jackson". Great reaction!

As a DJ you'll love their Daft Punk Medley. From way back in 2013 and their first Grammy.

One song to add to all the comments below...their version of Amazing Grace is absolutely out of this world.

Pentatonix is amazing!

All a cappella. When they do use the rare instrument, will be prominently displayed in the video. Kevin, the beatboxer, will occasionally play his cello. They have been together for 10 years and have a couple of hundred song catalog.

I always love listening to the reactions of there first time listeners.

First time hearing Pentatonix!! Welcome to our world - we are Pentaholics. Beat boxing? Incredible voices? Transitions? Vocal sounds? They are talented? Everybody can kinda sing a little bit? That guy is a problem? LOL --- You haven't heard anything yet!! PTX has a catalogue of over 200 songs. Suggest you react to every single one to answer all those questions. See you down the rabbit hole.

PTX one of the best Acapella groups 🔥

If you want to see what each member can do, react to their cover of Come Along. It is a whimsical enchanting song that doesn’t really fit anywhere.

Welcome to the world of Pentatonix, or PTX for short. Get ready for a quick boost to your channel from their rabid fans who call ourselves “Pentaholics”. Here is my quick intro to the group for new fans. PTX is a five member “a Capella” (without instruments) vocal band formed in 2011 for the NBC television reality competition show “The Sing Off”. The original members are “the trio”, who went to high school together in Arlington, Texas made up of: SCOTT HOYING, male, 6’3”, usually blond, sings baritone, but has a wide vocal range and covers the bass line of songs when the normal bass is singing a lead. MITCH GRASSI, male, 5’10”, normally black hair but has changed body mass, wardrobe and hair style so much in videos he’s often mistaken for different people. Mitch has an amazingly high range (contra tenor) that some mistake for a second female voice. KIRSTIN MALDONADO, female, 5’4”, natural hair color is black but changes it often in videos. Kirsti (rhymes with “thirsty”) sings mezzo soprano and, for a time in 2018 between the group’s tours, had the female lead on Broadway in the production of “Kinky Boots”. Added to “the trio” for the show were: AVI KAPLAN, male, 5’11”, long dark hair, beard, usually wears a knit hat of some kind. Avi is a classically trained “basso profundo”. He provides the vocal bass line as well as added vocal percussion but often uses his upper registry to sing vocal leads in a number of arrangements. Avi is the ONLY member of the band that has change. He left on good terms in 2017 for reasons related to conflicting demands of the band’s touring schedule and his personal/family commitments. He assisted the group in finding his replacement Matt Sallee. KEVIN OLUSOLA male, 6’1”, black, changing hair style, is known as “KO” and was asked to join PTX to provide vocal percussion after Scott watched a KZfaq video of him “cello boxing” (beatboxing while playing his cello). KO is the classic over achiever of the group. He plays Cello, Piano, and Saxophone all at concert levels. He graduated pre-med from Yale, speaks Spanish and spent over a year in China where he became fluent in Chinese. He sings Tenor but vocals were not his strong suite when he started so he worked with other band members and a vocal coach until while on tour he would perform the featured vocals in "if I ever fall in love", (originally performed by guest artist Jason Derulo for the album and video). He also writes and produces music both individually and for the group. So, KO is more than “just the beatboxer”. The most recent member and the only change in the group’s membership is: MATT SALLEE, male, 5’9” black with usually close-cut black hair. Matt replaced Avi Kaplan in 2017 to provide vocals, vocal bass and percussion. Matt can be heard using his exceptional upper vocal range to provide a rich tenor/baritone lead often ending with a slide down to a deep bass punch. Things you need to know because if you get these wrong Pentaholics will come after you with pitch forks and torches! 1- There is NO Auto-Tune; what you hear is actually what they sing. They really are that good. The only exception is they may deliberately use Auto-Tune when they cover songs where it was used in the original and is key to the sound of that song. An example is "90's Dance Medley" when they use it in Cher’s, “Believe”. 2- What produces everything that you hear in the video, you see in the video. If there is an instrument used in the music, you see it on screen. Enjoy the ride.

Welcome to PentaTONix! More, please! Would love to hear your reaction to some of their earlier covers like Bohemian Rhapsody, Daft Punk medley, Sound of Silence and Evolution of Michael Jackson. They do some phenomenal one-take medleys that really showcase their talent and are total FIRE!

ACAPELLA YES!!! Check out Hallelujah, Amazing Grace, Sound of Silence.. and also check another really good Acapella group called: Home Free!! Both are excellent!!

So many Pentatonix songs and you would probably really enjoy Kevin Olusola (the beatboxer) doing his solo version of 'Down'.

more PTX, please!!! i recommend their covers of Daft Punk, Evolution of Michael Jackson, Gold, Can't Hold Us.... but, literally everything they do is amazing :)

Great reaction! They are the best a cappella group in the world. Winning 3 Grammy awards and great acclaim for there unique blend of voice and beat boxing/percussion from just their mouths. Also known as PTX, their fans called the Pentaholics, are a passionate, fun, and nice people that love them really much. They will give you all the pertinent information you will need about this talented group. Enjoy your ride down this enjoyable rabbit hole!

Daft punk medley, evolution of Michael Jackson, evolution of Beyonce, evolution of Ariana Grande, Evolution of Rhianna have great transitions too!!

Yes, they are Crazy. Welcome to the rabbit hole! Some of their more icon ones are: Daft Punk, Bohemian Rhapsody, Hallelujah, Sound of Silence, and Gold. Hope you keep going on PTX! 😁

Came back to watch again for like the 5th time. Your reaction is SO much fun to watch haha. It's basically me when I first saw them on TV on the Sing Off.

I've listened to this medley about 5000 times and it still gives me goosebumps every time.

Their arrangements are sublime. I can't even imagine their process to get to these amazing pieces. Their originals are equally satisfying.

Pentatonix is the five note scale. Five members mostly with just their voices.. Yes the first way you pronounced it was correct.

5 voices creating a wall of massive sound!!!! Yep, vocals only.!! Kevin is the beat boxer, Matt is the bass, all vocals...all. Excellent Reaction man!! Rihanna evolution is fire! all their covers are upgrades. Pentaholics, 19 million of us, will come if they are played..so enjoy the ride! Just a note "Hallelujah" is a must. The only change in their lineup is from former bass Avi to current bass Matt(seen in this video)

If you are impressed with their transitions then you will love any of their evolution videos.

I believe their version of ‘Hallelujah has close to 1 Billion Views…

Yes, they are a cappella. Kevin, the beatboxer, is phenomenal. They did use auto tune on this medley as an homage to Cher, but typically they do not use it. They are fantastic.

Yes that young man does all the beat boxing and they have nothing else no instruments or anything except their voices, love this group

Want to know more….join us! Jump down the rabbit hole, PTX has two albums of only originals and many mixed albums with their amazing covers/mash ups & originals. Something like 200+ songs and such wonderful live performances…Hope you take a chance on more of their work. Fun watching this with ya!!!

Kevin is the beatboxer. Matt is the bass. Kirstin in the Alto. Scott is the baritone who covers bass when bass has a solo (tall blond). Mitch is the counter tenor, tenor and occasionally a baritone. Thank you for reacting to Pentatonix (Pen -ta-tonix). You can just call them PTX. Please react to their cover of "The Sound Of Silence".

Considering your expressed interest in music genres and the transitions, you should watch the Daft Punk medley. The Grammy they won for that one was renamed to "Best Arrangement, Instrumental or A Capella" from "Best Instrumental Arrangement" just so they could get the nomination. They won it again the following year for their arrangement of Dance Of The Sugar Plum Fairy. (Their third Grammy wasn't for arrangement, but was Best Country Group or Duo for their collaboration remaking "Jolene" with Dolly Parton.) As someone else already said, you would probably also enjoy their one-take live Evolution Of series of medleys. Other than that, maybe their original EDM Love Again. Or they have more than a hundred other options spanning every genre and both covers and originals before you even get into their Christmas offerings. Name something you are interested in and fans will jump all over the suggestions.

Are we watching the birth of a new Pentaholic? What a beautiful sight and sound! Welcome to the rabbit hole.

Better late than never so, welcome to PTX! I look forward to seeing you equally exciting reaction to more of them!

I can't wait to see more of your reactions to Pentatonix... there are so many songs to pick from that I cannot even to suggest a few

Another PTX fan in the making! I can't wait to hear you react to more of this amazing group.

I think you'd really enjoy Pentatonix medley "new rule's x ate you that somebody"!!! I'd love to watch your reaction to any/all PTX songs... you're fantastic!! Thanks for giving them the chance and .. welcome to the Pentatonix religion 😎

If you like the sound effect vocals check out Bohemian Rhapsody but to be blown away by the voices checkout hallelujah.

You NEED to hear their rendition of Hallelujah!

“What the fuck?!” Is a perfect reaction to PTX! Love your appreciation for them! Mitch is “the problem”?! Dude you just got Mitch Slapped!! Welcome to the club!

You are right with the first pronouncement. Check their cover of “Hallelujah” and “Bohemian Rhapsody”. Both incredible.

Really enjoyed your reaction! You're right, I think - a background as a DJ gives you a unique perspective on what they do, so thanks! Subbing hoping to follow you on an epic journey! How you approach their huge catalog depends on what catches your interest...here's a ...maybe not brief, but concise(?!) roadmap for you: * Hallelujah - over 600 million views, their most watched video * Sing Off season 3 episodes - added a talented bass and beatboxer to a trio of high school friends, basically met and auditioned, you can see how they started great, learned as they went, and won (watch the judges comments!!) * Somebody That I Used to Know - early posting as they tried to make it on their own after the recording contract they won was canceled because there "wasn't enough of an audience for a capella" * Daft Punk - won them their first of 3 Grammy awards (search "private performance" and compare it to the official video - it's really all them!) Yes they can do EDM! * Can't Hold Us - they can rap, too! * "Evolution of" - take your pick! MJ, Rihanna, Beyonce, etc * La La Latch - they "mash up" even better than they "medley" * Sing - from first original album, shows their appreciation of their fans, can't sit still when you listen! * Popspring 2016 - 3 other originals plus Evolution of MJ live, they were on fire that night! Well-mixed and mic'd * Imagine - shows their heart, just what you need in this season of politics to lift your spirit back up * Bohemian Rhapsody - they kill with their own style but honor originals!! * Mary Did You Know, Amazing Grace - their Christmas songs are gorgeous * Oh Come All Ye Faithful - best ever version, pays homage to beatboxer Kevin Olusola's Nigerian heritage * New Rules x Are You That Somebody - first mash up with new bass (only member change, the others change styles like socks ♥) and it's fabulous * Coffee in Bed - from second original album, fairly recent, shows they grow and change but keep getting better! Collabs - all great! You'll see one you like :-) That's not brief, sorry, but it gives you a little overview

Oh so many more wonderful covers and original songs for you to enjoy! PTX are amazing...

Welcome to a cappella. I think you’ll like the “Country Fried Pop Medley” by Home Free, too. PTX is awesome! VoicePlay’s “Oogie Boogie’s Song”. You’re in the rabbit hole now.

Daft Punk Medley! You should check out their arrangement! They have an original called Love Again that would be right up your alley! Thank you for this reaction! Please do more PTX! Pent a ton ix, that is how you pronounce it! How that helped!

If you want to hear versatility, check out their arrangement for 12 Days of Christmas.

I love watching you react to these songs. You know them and it makes me happy that I'm not alone in knowing these songs

For another DJ mix style song, see their medley of Daft Punk. The arrangement won a grammy. Matching keys and tempos was really tricky. Matt Sallee is the bass in this song, but before 2018 Avi Kaplan was the bass. The bass is often doing bass guitar, but also integrating with Kevin doing bass parts of the percussion/rhythm track. But also some leads. Kevin Olusola is the beatboxer and occasionally plays cello at the same time (e.g. Say Something, Radioactive, Papaoutai). He sings tenor when he isn't beatboxing. Scott Hoying is the baritone, but gets up to mid-tenor and also covers bass when the bass is on a lead. Kirstin Maldonado is mezzo soprano, which is a high alto. She has a lot of warmth in her voice for this range. Mitch Grassi is a very high tenor while still having a very good low tenor voice. Besides Daft Punk, they have an original EDM song called Love Again with very strong and strong and unusual synth percussion from Kevin. They did a very solid version of Bohemian Rhapsody that was recommended by Brian May. Massive drumming. They do a whole bunch of Evolution of ... songs (Music, Beyonce, Michael Jackson, Ariana Grande, ...) as well as fun things like 100 songs in 10 minutes. They do some of these live. They do most of their songs live. One of their most fun and motivational songs is their old concert opener - Sing!

Yes, Mitch is definitely a problem 😁 Totally addictive and immensely talented - as they all are! PTX is such fun, their covers are amazing and their original music is wonderful as well. As others have said, it is Pen-ta-tonix, in reference to the five part pentatonic scale. Two covers that I think really show off their talents are Kiiara’s ‘Gold’ and ‘Can You Feel the Love Tonight’, but honestly, you could pick anything they’ve done. Thanks for the fun reaction!

Great reaction. I can't wait to watch your future reactions to their masterpieces. Below are some suggestions (there are sooo many): BOHEMIAN RHAPSODY, HALLELUJAH, DAFT PUNK, SOUND OF SILENCE, IMAGINE, CHEERLEADER, EVOLUTION OF MICHAEL JACKSON, SING, HAPPY NOW, BE MY EYES, THANK YOU - to name a few. Thanks!

Always love watching someone discover the a capella madness that is PTX (you can shorten it to PTX). You should check out their Daft Punk medley, and their original Love Again, if you love the dance tunes. Both of those have the original bass Avi, but they are both masterpieces. They won their first Grammy for Daft Punk. Loved your reaction to them. Kevin is a beatboxing genius, and Matt (the current bass) is superb

Yes, this group is indeed a capella. Kevin is an amazing beatboxer.

So many songs to react to but I think you would love New Rules/Are You That Somebody which really highlights Kevin & Matt.

in most of their songs they don't use any autotune or effects, and yes, they make all the sounds with their mouths. you should sheck out their version of "Halleluja"

the spin-off songs especially BORN TO BE WILD Kevin's beatboxing and Avi's bass make for a magical experience

Mitch - he's the problem child. LOL He is spectacular!

One of the best reactions I’ve seen to this. Calling Mitch a problem, I love it. You’re welcome :) As a DJ, your next one has to be their first Grammy, “Daft Punk” medley. You’ll really appreciate why it got the Grammy (for arrangement). The Grammys even changed the category so they could win it, it was previously “Best Arrangement, Instrumental.” Now it’s “Best Arrangement, Instrumental or A Capella.” Oh, and the people calling Mitch a countertenor aren’t doing justice to his range. He goes from baritone to sopranist (male soprano, I found out recently that head range is included when determining a sopranist’s range), and even beyond that. He might be able to pull off some Mariah Carey whistle notes (extremely high and shrill) with practice. Tenor/countertenor is just the middle of his range. Btw, I’m glad you’re seeing some fast results with Pentatonix (you got it right first try, then kept changing it, lol). Weird Al won’t bring in the bigger numbers (yet), but there are good reasons I mentioned him, if you trust me. Just hold off on “Rap God” until after you’ve heard at least “Couch Potato” and “Hardware Store,” maybe even that whole album (since it did win a Grammy for “Best Comedy Album”). I guess I’ll go watch that “Rap $#!?” now, since you had such a fast turnaround on some PTX for us :) Oh, and don’t forget to please rewind about 5 seconds or so (10 is fine, too, since it’s a button) after a pause, you don’t want to miss anything :p

They do have originals - Sing, Happy Now, Love Again, Run To You, Water. I would suggest reacting to PTX on The Sing Off (season 3), here you get to see how they started and there is some great performances. Thank You for the reaction

Welcome to Penta-holics!! No instruments, just their voices. Try Sound of Silence.

There is a huge catalog of videos by Pentatonix, but since you are enjoying the transitions so much, I would recommend their evolution videos. In random order: The Evolution of Michael Jackson, of Beyonce, of Music, and of Rihanna. Alto/Soprano(?) - Kirstin Maldonado Tenor (countertenor) - Mitch Grassi Baritone - Scott Hoying Bass - Matt Sallee (joined the group in 2017, so videos before that have Avi Kaplan.) Beatboxer, tenor and master cellist - Kevon Olusola They formed in 2011 and won season three of The Sing-Off.

These folk are the best group in the world

They give me goose bumps!!!

Welcome to the insane world of PTX.....we are the Pentaholic’s. A over protective fan base. We are loyal to any new reactor who finds them for the first time. PTX has a 10 year catalog for your jump down their rabbit hole....enjoy your journey......Judy D

I didn’t want it to stop !!!

Yeah, Pentatonix is an acapella group where they use there mouths to make all the music you hear. Kevin Olusola is their beatboxer who is out of this world amazing at the things he can do. You should check some of his solo work. He is also a DJ like yourself. Check out his solo cover of Marian Hills' "Down". This man, right on the spot created all the sounds and beats you're gonna hear. This guy is incredible. Thanks for your reaction here. Hope to see more Pentatonix from you my friend. Peace

I love your reactions! I’m feeling it with you. They are Pen-Tah-Ton-Iks. Be prepared to be amazed. Please react to some of their other songs - like Mary Did You Know and Hallelujah. Not as jazzy but you will not be disappointed.

The beat boxer, Kevin, can beat box while breathing in so he can keep a wall of sound that makes this a capella group have such a full sound. And the harmonies of the other 4 are so tight.

They are the best at what they do, no equal.

Love your reaction! Please please do more from them, you have stuff from 10 years to choose from.. and I had to laugh when you said "he's a problem"! 😁

Mad world 🔥🔥🔥

glad i clicked on this...reaction was FIRE!!! You can not go wrong with any song Pentatonix does!!! Another EDM sound i love from them is "Love Again" i know u will enjoy it too...they just dont do covers!! Love again as i mentioned before is an original written by them. I am subbed and ready for more!! Stay safe and healthy

Everything Ptx does can be replicated live on stage.

They are widely considered the number1 accapella group in the world.

Kevin and Matt are super talented ❤

They are indeed beat-boxing. No instruments. All voices. What you see is what you get/hear. They may be the premier a capella group in the USA today. Or maybe in the world. If you want to REALLY get your mind blown, try their Daft Punk medley, which show you their range. But just as impressive is their versatility, because they have 3 Grammies for 3 different genres of music. If you are astounded by your first exposure, start exploring to see their range. You will not believe your ears - but it is all true. Further, they don't release a video if they can't perform it live. So watch for some of their videos that were made at a live show. THAT will tell you the truth of this group. Enjoy, sir, and look around PTX Official to see what else they can do.

No instruments. All vocal talent. They are fire! More Pentatonix (PTX) please!

Love you calling these golden oldies.... ROFL.... I had kids already when most of these songs came out. To me golden oldies is like 40's, 50's, maybe 60's.... oh to be young. Great reaction

Have you seen pentatonix do amazing grace yet???? That is fire...will make you cry...how about hallelujah???? Fire, too

Keep your PTX journey going with Bohemian Rhapsody...Sound of Silence...Amazing Grace...Hallelujah...Cant you feel the love tonight or any of their other songs. Great reaction. Thanks and stay safe.

We stan a first impression video!

You called for Penta-holics? I have arrived!! 🖤🔥🖤🔥🖤🔥🖤

They have 19.1 MILLION subscribers! Welcome to the rabbit hole!

Kevin Olusola is sick. Watch their cover of Kiiara's "Gold". Mitch does the vocal chop with his voice...no effects.

The beat boxer's name is Kevin, and he's know as the Human 808. He's incredible. I mean, they all are, but he's just the GOAT.

The black guy wearing the white coat is kevin. He is a beat boxer. He is doing the percussion you are hearing. The other black guy, matt, is the bass singer. He uses his voice to make the bass guitar sound you are hearing. Mitch is what is called a counter tenor. He can sing insanely high notes. Matt the bass singer sings extremely low notes, as well. Kevin also sings tenor, raps and plays cello. Check out their cover of bohemian rhapsody, sound of silence, imagine, daft punk medley, hallelujah, dance of the sugar plum fairies, butter x dynamite, despacito/shape of you, havana. Those are just a few to whet your appetite for them on.

Excellence is going on
