Pentatonix has done it again.  Another amazing rendition of a Christmas classic gone viral.

Pentatonix, winners of the 3rd season of the "Sing Off"  have followed up their "Little Drummer Boy" video with another winner. Their latest is "Angels We Have Heard on High." This a cappella group is just fun to watch and music to the ears. You may find yourself watching their videos over and over again. And if you would like to see them live, they will be performing for two nights at The House of Blues in Boston on Saturday & Sunday, April 5th & 6th, 2014.
