A cappella group Pentatonix take us through a virtuoso ‘Evolution of Music’ in this charming and very cool musical medley! These five talented vocalists won a season of NBC’s The Sing-Off and when you hear them singing, you’ll know why.
If you enjoyed Pentatonix’s vocals you’ll want to listen to Home Free’s Johnny Cash cover and Project SH. These a cappella groups are great too!
