It just wouldn't be Christmas without Pentatonix.
The group hosted their own Christmas special last Wednesday, and their second Christmas album A Pentatonix Christmas is at number three on the Billboard chart right now. Last week, the group stopped by The Today Show to perform "Up On the Housetop," one of the hits from the new album.
Up on the House Top is actually one of the oldest Christmas songs of all, dating back to 1864, but the band give the song a very modern feel, complete with a reindeer name breakdown towards the end.
They even include the sounds of the reindeer's feet on the roof - thanks to Kevin's vocal skills - something that only an a capella band could pull off.
