Avi (he was the one with the beard and beanie in Hallelujah) left the group in 2017, for personal reasons. The new bass is Matt Sallee, the guy in the white jacket. Everyone else has been with the group since the beginning. Mitch (guy with the big hat) is the guy here in all black. Kirstie was blonde in the first video, she changes her hair pretty much every video (as does Mitch). They both change their looks often to the point you wonder if it’s them. The tall blonde guy is Scott and the amazing beatboxer is Kevin, a musical genius.

You should react to their song Havana. The new bass is really awesome. And BTW yes the guy with the mullet looking hair style is "sombrero dude"

I know everyone is telling you stuff and yes Matt the new black guy replaced Avi the bass with the beard and beanie, and yes Mitch was the sombrero guy....I know your working your way through your list...make sure Imagine and Bohemiam Rapsody (Mitch does an electric guitar)...now your a Home Fry and a Pentaholic!

Very nice rendition of Simon and Garfunkel's Sound of Silence. The band Disturbed also did a rendition that is absolutely phenomenal.

You’re gonna be blown away by their Daft Punk Medley. They won a Grammy for it!

React to ANY Pentatonix video, its going to come out the same but... Their version of Amazing Grace has brought tears to many a good man's eye.

If you ever have to ask, Is that Mitch? (Sombrero hat guy) the answer is yes! He changes his look a lot. Avi (the beard and beanie guy) left the group amicably and was replaced by Matt (guy on the left). That’s the only line up change! Awesome reaction!

Their version of Amazing Grace is killer!

"What am I watching?" A masterpiece! Your confusion is really cute and that was a great reaction, I hope there's more to come!

Love your reaction! But you have to wear headphones because if you think they sound good now, you are not going to believe your ears. Can't wait for your next reaction, you crack me up.

"They probably don't need to say nuthin'" - Yes!

Pentatonix

If you have to ask if that's Mitch, then it's Mitch. :) Avi left the group amicably in 2017 for personal reasons. (There's a KZfaq video where he announces it to fans. If you watch it, have tissues. It rips your heart out, stomps that thing until it's ragged, and then stuffs in back in your chest. They're all crying) He has a beautiful solo career, he's happy and he couldn't sound more amazing. So, pretty much any video 2017 and before will have Avi, after that will have Matt.

Yes! If you want to be totally blown away Watch Daft Punk Medley next!

Two of my favorite Mitch moments in this song.

Welcome to the PTX rabbithole! its a deep one. New Rules x Are you that somebody is my personal favorite, but Amazing Grace, the 90s Dance Medley, Can't Hold Us, Havana, and so many more are all amazing

Another great performance is their Amazing Grace. You will encounter their wall of sound and another Kirstin moment.

I love it when people appreciate everything about the song itself; the beats, the vocals...

Listen to imagine by PTX. They are so amazing. Imagine is a cover originally sang by John Linnon , they kill it baby. Also. Mary did you know, another phenomenal performance

KC girl here, love watching your reactions of them and Chris Stapleton! Can tell you have such a passion for true musicality. Go Chiefs!
