PTX: A DAY OF "REST"

The turkey may not be cooked yet, but the Christmas season is already upon us, and RCA's Pentatonix (whose new holiday album is now exploding) have delivered a virtuosic video of "God Rest Ye Merry Gentlemen." The a cappella marvels will perform on Kimmel on 12/7; their A Pentatonix Christmas Special airs 12/14 on NBC.

The group also surprised diners at a Tennessee Cracker Barrel this week with a live rendition of "Santa Claus is Coming to Town."
