Pentatonix new member matt sallee

I think there may be some confusion here!

Pentatonix is a vocal group known for their a cappella music, and they have not announced a new member named Matt Sallee. The group's current members are:

Matt Sallee is actually a singer who was a member of the a cappella group Home Free, which won the fourth season of The Sing-Off in 2013. He has also performed as a solo artist and has released his own music.

So, while Matt Sallee is a talented singer, he is not a member of Pentatonix.
