"Pentatonix's debut album, That's Christmas To Me, featuring a collection of seasonal favorites and unique arrangements of modern classics, as well as their current original holiday single, 'That's Christmas To Me,' is available now from RCA
If the name 'Pentatonix' sounds a little familiar, it's because they were an a cappella group on TV show 'The Sing Off'. Since that show they've been on tour and releasing new music videos of their harmonies to popular songs.
