Avi isnt just a bass, he is a baso profundo, which is a special kind of singer. His voice is so resonant, when he hits the low notes, the vibrations go through your body. It is amazing live

Mitch is a natural counter-tenor. Experiencing his voice for the first time is called being "Mitch slapped."

Mitch (the fourth soloist) is what is called a countertenor in the classical music world. That is, he’s a man with a female soprano range. It’s truly beautiful and completely insane how high this beautiful man can go

Wow! I’m a teacher and your transparent approach to research, going to the primary source and its analysis and then supplemented by your Pentatonix research. Just wow! Gentlemen, just a STELLAR demonstration of HOW to do a reaction. I’m following you NOW.

Mitch has the angelic voice. Your reaction to Mitch's voice is called the "Mitch Slap"--you've been inducted. In their cover of "The Prayer" he sings Celine Dion's part and his voice is even more angelic. Bohemian Rhapsody, Imagine, Daft Punk, all of the evolution of series, especially evolution of Michael Jackson, Shallow, Say something, their original "Sing" and many more. You can't go wrong with any original or cover. Pentaholics (PTX fans) call them upgrades vs covers. Kevin is the beat boxer. He does all of the percussion (drums, symbols, etc...) with his mouth. He also plays the cello in some of the videos. You ask if that's legal, we say yes. This group is so amazing, they can probably make the sounds better with their mouths. Check out their original "Coffee in Bed." Kevin is amazing. Later down the road, check out Super Fruit. Mitch and Scott (first singer in Hallelujah) formed an off-shoot from Pentatonix. Check out their cover of "Rise" and "The Promise." That should keep you busy. Enjoyed your reaction. Liked and sub'd.

Dude! Kevin Olusola is the group's beat boxer/ percussionist. You'll be amazed by him. Welcome to the PTX rabbit hole.

I can’t listen to Pentatonix sing “Hallelujah” enough. I will never tire listening to it. A+ to Leonard Cohen as well.

This group is PROOF that God DOES EXIST !!!!

Avi Kaplan the bass in this video left the group in 2016. Matt Sallee became their bass in 2017. He is equally as talented.

Fun fact: When Avi Kaplan sings his solo part, Scott Hoying takes over his bass line. Also, if you want a great demonstration of Kevin's beatboxing ability, listen to 'Daft Punk Medley'.

I just want to hear Jordan and Jared read bedtime stories. Very soothing/calming voices.

This is the most perfect song ever but Pentatonix "Sound of Silence" is also pure magic

Their version of Imagine by John Lennon is unreal. Some reactors get emotional.

This gives me chills no matter how many times I hear it tbh Their Daft Punk Medley will blow your mind far wider than this did lol. Also check out Bohemian Rhapsody and Sound of Silence!

My favorite group in the whole wide world. So blessed that they share their God-given talents with us. ❤😊

Listening to Pentatonix is truly a religious experience... you're transported to a different place.

Kevin can do a powerful bass kick with his mouth. In cases where more complex percussion is needed, he will beatbox and have a stomp pad for the bass kick. More often than not it is his mouth. Also, sometime Kevin’s bass kick is backed up by Avi’s (the bass singer in this video) to make a more resonant sound hard to distinguish as 2 voices.

For everyone who begins their PTX journey with 'Hallelujah' (a popular first due to the 667M YT views), I strongly suggest making their 'Daft Punk' medley the second PTX performance to experience. 'Daft Punk' earned the group's its first Grammy and it helps new Pentatonix "subscribers" appreciate the group. Welcome to the PTX journey! (BTW, the sounds are from Kevin and that world-class rich bass vocal is from Avi and Scott when Avi is singing lead.)

Welcome to the world of acappella highs, lows, beat boxing, profound basists, alter tenors, all together. Beauty.

Pentatonix’ Sound of Silence will leave you speechless!

Wow guys. Doing so much research about the song, Leonard Cohen and Pentatonix before listening to the song is impressive. Good job.

I'm sure this has already been said but: Verse 1 - Scott Hoying, Baritone and covers baseline when Avi has a solo. Verse 2 - Avi Kaplan, Bass and beloved member of PTX. He left the group amicably in 2017 and was replaced with Matt Sallee. Verse 3 - Kirstie Maldonado, Mezzo-Soprano Verse 4 - Mitch Grassi, Countertenor, has been called a once in a generation talent. Whole song - Kevin Olusola, beatboxer and percussion. Also sings, speaks a myriad of different languages and plays the cello. Dude is a beast. PTX is 100% acapella. They never create anything in studio that they can't recreate in a live performance. For recommendations, check out the following: Daft Punk Medley Dance of the Sugar Plum Fairy Any of their Medley videos Gold The Prayer Run to You Aha - live in Singapore at the Star Vista Really, anything. They are incredible. Welcome to the PTX rabbithole. The Pentaholics are glad you're here. Btw, you just got Mitch-slapped. ❤

Great reaction. Also, classic reaction to Mitch’s amazing gift. We call your surprise to his voice the “Mitch-slap”. 😀 Anything you choose next will be great, esp Bohemian Rhapsody, Imagine, Sound of Silence, Daft Punk. But my fave which not too many talk about is Dog Days are Over from their Sing-off competition. Listen for Avi’s “throat-singing” in the beginning, Mitch’s breath-taking solo, Kevin’s relentless percussion/beatboxing, Kirsty’s lyrical support throughout and above all Scott’s tireless energy singing lead. He really takes you on a ride and leave you spent at the end. Unbelievable performance. Wish they would do it again!

The amazing bass you're hearing is the group bass singer, whom is Avi Kaplan in the video (he left the group for a family emergency). He really sings that crazy low. He's the bearded guy with the beanie. The blonde guy (Scott) picks up the bass when Avi had his solo. Scott has an amazing range so he can pick up but the severe highs that a tenor can reach.

I strongly, strongly recommend their covers of “Sound of Silence” (with Matt Sallee), “Imagine” and ‘Mary, Did You Know?”!!!

You have been officially Mitch slapped. Mitch Grassi the countertenor has an otherworldly voice. This isn’t even the extent of his range. They are all amazing singers, including Kevin Olusola, the beat boxer. He just doesn’t sing often. Avi, the guy in the beanie, left the group in 2017 for personal reasons, and Matt Salee, the current bass joined the group. He is also amazing. They have over 200 songs in their catalogue. You must go down the ptx rabbit hole. Their fans, Pentaholics, will follow. Loved the reaction. Keep them coming. Bohemian Rhapsody is great, Imagine, by John Lennon. Come Along, New Rules x Are You thatSomebody. So many to choose from. All are great. 💕💕

"Mary Did You Know" Soul moving.

Everytime I see people listening for the first time to Pentatonix, it makes me sooo happy! And you two didn't disappoint while being mitch-slapped lmao. Thanks for the reaction!

This concept that you guys do when reacting is very unique, how you look up the group first and also the original song before reacting..I love that!

Bohemian Rhapsody, Sound of Silence, and Imagine are definitely ones you should check out by them! Also Mitch (guy in the hat) and Kirstie change their looks pretty much every music video so you might not recognize them but they are always there

That look at 18:00 lol. That my friends is what the Pentaholix like to call being "Mitch slapped" You nailed it, he has got such a unique and amazing voice, it's always great to watch people react to that section.

You know they are amazing when you feel like you've just had a religious experience

Others have made excellent recommendations. I want to make a different one: Pentatonix singing 'Dance of the Sugar Plum Fairy', which as you know is a Christmas song. What is unique is that it is an instrumental song, there are no words in the song. None. Yet Pentatonix does an amazing version of it. And they won a Grammy award for it. Let that sink in for a minute:. An a cappella group won a Grammy award for singing a instrumental song that has no words.

Kevin, the beatboxer is not a bass, his vocal skills are tenor. The bass is as I said, the Great Basso Profundo, Avi Kaplan. Kevin Olusola, the beatboxer, is a Yale graduate. He was headed to Medical School. His plan was to be a Medical Dr. in China. He is fluent in Mandarin and a few other languages. Like Avi, his plans changed when Scott Hoying found him on youtube and managed to get his phone number at Yale. It was just a sing off and I think he thought he would continue with his plans when the group was eliminated, but that did not happen and now all of them a multi-millionaires. Avi was the only one who left the group and he is the one who suggested that PTX bring in Matt to take his place.

Man this reaction has to be the very best I have ever heard. They covered everything you need to know about the song, and even listened to the originator! Great job guys keep it up I’m a new sub after this video!

Research “beat boxer” Kevin was at the top of their list of results. That is how he joined the group. They got their start on the Sing Off, but found the rules required they have five members. That is how Avi and Kevin became part of the group. The deep bass you hear is Avi. He’s a basso profundo, considered a rare bass singer. He’s the second soloist in this song. Kirstin is a mezzo soprano, but Mitch frequently takes those parts. Your really should react to their version of The Prayer.

Mitch is generally referred to as the voice of a generation. His range is incredible! Have fun with this rabbit hole 😁😁

Since you guys are fans of doing the original and then comparing (which is a format I love btw), you must check out the PTX version of Gold (and the original). It really showcases how freakishly good they are!!

I have heard this version of this song many times and I never tire of it! You really need to listen to their other songs! They are amazing! Mary Did You Know.!

These are my go-to PTX songs when I need a lift. "Amazing Grace" "Hallelujah" "Mary did You Know?" "Can You Feel the Love Tonight" "Daft Punk" "Bohemian Rhapsody"

Stomping, clapping, pounding of the chest, all ok in Acapella. Great reation gents!

8 minutes in & I have to stop and comment. You let each other speak. You speak calmly and clearly. You value knowledge, so much that you stop to look things up instead of just jumping in blind. You notice things. Before I even see what you think of PTX, I'm a fan of you as reactors. Subscribed.

Oh I love how you guys took the time to really compliment everyone. I live everything about Pentatonix but I am so drawn to Mitch’s voice.

This is my first time watching one of your reaction videos and I'm so happy I found it! You guys are calm, quiet, have intelligent things to say and express yourselves very well. I say this in contrast to some of the reactors that just bounce around, blithering things and just have basically nothing to say except "WOW!" and "COOL!" and such. Plus, you don't interrupt a whole bunch of times, which I REALLY appreciate! I hate reactors that pause every 30 seconds just to repeat the same things they already said. You have a good amount to say when you DO pause, but your comments are well thought out and add to the video. It's much preferred over breaking the song up into little sound bites. I really enjoyed this and am going to go look into some of your other videos!

"Where to go next?" - the only correct answer to that is - "Anywhere", everything they do or did is pretty incredible, the genres they cover from hymns, carols through pop, hip hop, rock, contemporary ballads are amazing - note: all their official videos can (and do) get performed live also, without the high level of mixing of course. Keep in mind, they aren't the only awesome a capella group out there - there are a few, every one of them incredible in their own rights, and interpretations You will find fans for each of the groups will insist their favourite is best - my favourite is the the beautiful music. There is also what I refer to the Limbo and Pole Vault Syndromes - "OMG!!! How low/high can he go?" and then the "This one is the best" fans

As far as using "body Percussions", what most people don't realize is that the beatboxer actually makes the percussion sounds with his mouth and voice but adds the movements as a visual key to those watching. Consider the fact that in this video Kevin is patting his chest with leather gloves on and a leather trench coat as well as stomping his foot on the ground in the desert. It would be impossible to mic him for all those different sound dynamics. But further, you hear exactly the same sounds produced by him in the video where they perform this song live in their Christmas Concert but he is patting his bare hands on a fabric coat and stomping his foot on a stage floor. If you watch his mouth in the live recording you can see he is creating the different "body percussion" sounds with his mouth. Once I realized this I was even more impressed by his beatboxing skills. Everything they do is phenominal. BTW, keep up the fantastic reactions guys. You are Great.

There are no “rules” in making music, but there are definitions. PTX uses instruments from time to time, but they always make it known. 😊

love, Love this version!! totally moves the heart and soul!

yes, body percussion, clapping, stomping etc. is allowed in acapella. PTX use it alot. they also use instuments from time to time, but you'll see them in the video - so if you don't see an instrument there isn't one.

If you are impressed by this, you should see them live! They sound EXACTLY the same!

I was blessed to see them live a few years ago. Simply amazing. It was an outdoor concert and a storm came up and they were told to get off the stage because of lightning. They were so apologetic and left the stage. As everyone started making their way to the exits they came back out and said they could not leave without at least singing Hallelujah for us. It was breathtaking.

He was 89 when he did this one in 1977 is the best one

For more breathtaking beauty, have a listen to their rendition of "The Sound of Silence".

Finally!! I’ve been waiting for this for a long time guys. You can’t go wrong with Pentatonix, welcome to the best Acapella group there is. My suggestion for next, is The Prayer.

It's 5 of them but they sound like a symphony. This performance always gives me goosebumps, even after hearing it dozens of times.

The Prayer is my favorite Just beautiful

I read somewhere that Kevin, who does the beatboxing, uses his hands and feet to keep time, or 'play' each percussion instrument he is doing at that time. Each hand, each foot, is a different snare, cymbal, bass, woodblock, etc. In most of these groups practically everyone has picked up some beatboxing skills, in particular the bassists. The 'floor' that a good bassist and a good beatboxing percussionist can lay down to support the rest of the group can be amazing.

Kevin Olusola mostly does vocal percussion and sings in various songs with PTX, however he does use his body as well as the others on rare occasion. Kevin is perhaps the most overall talented. Check out his solo version of 'Down' (Marion Hill cover). You will be amazed.

I am a huge Pentatonix fan. Having said that, in my humble opinion, the best cover ever was done by K.D. Lang. She did it live in front of Leonard Cohen, who said it was the best version of his song.

I will never get tired of people's first reactions to Pentatonix cause they're amazing. Kevin is the beat-boxer and it blows my mind every time he can do that. And of course, the Mitch-slap. The great reaction to Mitch's amazing voice. Lol. Love them and love that you guys do too :)

Kevin is probably one of the world’s best beatboxer. He also “celloboxes”, where he plays the cello while beatboxes. That’s actually how Scott (the blonde), Kirstie (rhymes with “thirsty”), and Mitch (guy in the hat) found Kevin- he was posting videos on KZfaq. They met Avi (said like Ah- vee) through a friend, right before they competed on The Sing off. Avi (now Matt, the bass who took over Avi’s role), sings the bass notes or rhythms, Kevin does the percussion/drum sounds. Kirstie, Mitch, and Scott do solely vocals, but Scott takes over bass when the bassist is singing lead. Hope all of that made sense. Check out Amazing Grace or The Prayer. Both will give you goosebumps!

Yes, each member has a role, but they will often change up who takes on which role. Avi is the outstanding basso profundo voice you hear, but when he is singing lead, Scott, who is a baritone with a phenomenal range, will fill in the bass line. Likewise, Kevin is the primary beatboxer, but Avi will often work with him, jumping from bass line to percussion as needed. In fact, every member of the group has done some effects, as you can see in their Daft Punk medley... the only way for five voices to recreate an EDM sound! Please do more Pentatonix. I love your approach to reactions. Liked and subbed.

After hearing their version, it becomes everyone’s favorite version of this Cohen song.

Listening to Pentatonix is sooooo freaking special…YOU FEEL IT THROUGH AND THROUGH🙌🏽❤️🙌🏽A person’s voice and body ARE THEIR INSTRUMENTS🙌🏽 I feel like shedding tears any time I hear this version❤️

Avi is original group’s bass. All those super low bass notes are sung by him. All the vocal percussion is done by Kevin. They are an amazing team!

Yes, the body and voice are the instruments used to produce all sounds in A Capella performances. From PTX, that you should check out, Bohemian Rhapsody, Imagine, Sing, Gold Radioactive, Mary Did You Know, New Rules x Are You That Somebody, and one of my personal favorites A Litte Space ft ATEEZ (3 members of the 8 member kpop group ATEEZ).

"If there were one thing we wish we could do, it would be to sing..." 🗣🎤🎵🎶 Don't worry about hitting certain notes. If, when you sing, it makes YOU happy, then SING!!! 🥰♥👏🏽👏🏽👏🏽

I LOVE this song 🥰 especially that angelic voice...They are all so Blessed 🙏

Definitely check out the live performance for this song! They sound exactly the same live! 🥲

Go to their "Daft Punk Medley" it will give you a better idea of the abilities of Kevin Olusola their beat boxer/(in some later songs)cellist. His solo work is equally impressive.

Everything they do is a Breathing Master Piece. I can't not cry everything I hear their songs even the joyful ones.

Both of you have such calming voices, I came here to see a reaction to the amazing PTX and left feeling like I went through a good session of therapy

Two of my favorite Christmas songs: Mary Did You Know and The Little Drummer Boy...when PTX does it, it's felt in your soul and it's chokes me up every time filling me with greatfulness.

I recommend their acapella cover of Imagine by John Lennon. It's the most beautiful semblance of voices other than this video

DUDES...Sounds of Silence...it will leave you speechless!!!

They are incredible ❤

The bass singer is Avi Kaplan, the second soloist with the beard. However, when he does the lead, Scott has the amazing range to take over the bass. Got to love all their individual voices but together...magic!

The percussionist plays a mean cello and has a great singing voice as well.

This came up in my feed because i listen to a lot of pentatonix, but I’m subscribing now because I love your approach. Love that you researched the group and the song in the video. Your voices are so even and soothing, it was a joy just to listen to you. Thanks!

You guys are awesome. Kevin, the beatboxer, also has a gorgeous voice! You can hear him on "Mary, Did You Know?" I recommend that, as well as "Daft Punk Medley." Those, along with "Bohemiam Rhapsody," will *BLOW YOUR MINDS* !

Leonard Cohen heard this version before he died and said it was the best version he had ever heard. YES please do Bohemian Rhapsody. You can also go back to the beginning and watch season 3 of The Sing Off. They met in person for the first time the day before they auditioned for the show.

I want to thank ya’ll for your respectful take on the song. To have a wondering mind, as ya’ll showed, is the greatest gift of all. I am duly impressed!

Amazing Grace is one that just blows your mind. Absolutely beautiful!

The bass is coming from the bearded guy (Avi) except when he was doing his solo.. then Scott (the first singer who is a baritone with a wide range) took over the bass temporarily.. The beatboxer is Kevin and he didn't sing in this one. He does sing tenor in some songs but is mostly busy with the beatboxing (is also an accomplished cello player). Mitch has the angelic voice.. he is a counter tenor.

Another fun fact for you: Mitch and Kirstie have about the same range, and they can often seamlessly trade off in the background (the same way Scott picks up the bass line when Avi or now Matt takes lead) but when you hear Mitch or Kirstie take the lead, their voices have such a different quality to them, and I love how different they sound. Their cover of The Prayer might be the clearest example.

Beautiful, thank you for sharing

Wow, what an amazing review and reaction you two do! This is my first time seeing you channel but I am blown away with the intention and detail you put into you reviews. Truly Amazing! Thank you so much, you are both so talented and entertaining!

For arrangements and musicianship: Daft Punk, Sound of Silence, Come Along, Wizard of Aahs or any of the "Evolution of" series. For vocal superiority and harmonies: The Prayer, Amazing Grace, Mary Did You Know. or Imagine. For PTX originals: Start with Sing and Love Me When I Don't. You cannot go wrong. I would enjoy seeing your reactions to Daft Punk (one of their Grammy awards) and The Prayer.

The bass is Avi and you haven't heard anything yet Every song this group sings will you asking how do they do that? They are simply astounding Avi has blown speakers at concerts from his voice. He also sings more than one note at a time, and undertones. Each singer is amazing on their own but as a whole untouchable in their craft.

The Prayer for sure! Amazing Grace!!

I’d like to thank you for appreciating the musicianship here rather than just how good they were. Also for appreciating Mitch’s voice the way it should be ❤. Most people just sit in shock rather than listening and enjoying what they hear

Leonard Cohen was known for more than music. He was poet, novelist, singer-songwriter and an activist and speaker.

Mitch Grassi’s voice is the most beautiful thing ever created! I’ve been blessed with hearing them sing this live several times and they are completely breathtaking! Their music got me through the hardest times in my life - they are truly special 🥰

Just Amazing!!

The Sounds of Silence......magnificent.

You guys earned big fat subscription today! What an incredible RV from you guys! One of the best I've ever seen! Bravo!!!!!

EVERYTHING this group does will blow your MINDS!!! New sub and can not wait for more!!! Stay safe and healthy

Their Christmas album is absolutely phenomenal... The Little drummer boy one of my favorites

As long as you don’t use any instruments at all everything else is allowed! These guys are perfection! Every song is perfect! They are incredibly talented and they work very very hard to make sure they can replicate all their songs live! Wait till you hear the Prayer! And your right Kevin is the best beatboxer in the world!

Yes Pentatonix is awesome however Home Free are amazing as well, Adam Rupp " the human drum kit" can produce some of the most amazing sounds, I suggest starting with there version of Man of constant sorrow.
