Entertainment Weekly doesn't often go around boasting about "exclusives" from a cappella groups, but Pentatonix isn't just any a cappella group. The Sing-Off winners, founded by Arlington Martin High grads Scott Hoying, Mitch Grassi and Kirstie Maldonado, have been selling out shows nationwide and they just announced some 2013 dates, including a return engagement at Dallas' House of Blues on March 13.
But back to that EW exclusive. It's an audio-only version -- a great version, at that -- of the classic Christmas song Carol of the Bells, which is from the group's upcoming holiday EP PTXMas. No embedding available -- yet -- but you can hear the song here.
