Sorry it's taken so long to post some of this video - My daughter and I attended a Pentatonix concert back on 3/13/13 in Dallas, TX at the House of Blues and I just came across this little snippet and had to share. This is amazing! Avi Kaplan (Bass singer for Pentatonix) will blow you away with his ability to sing 2 parts at once - Literally! Better know as he says as "Overtone Singing"... Enjoy!
