'The Sing-Off' winners Pentatonix release a holiday music video full of Christmas cheer

If you're running short on Christmas cheer, all you need is a little Pentatonix to make things better. The a capella group, who won Season 3 of "The Sing-Off," have released their second holiday music video, a rendition of "Angels We Have Heard on High."

There's not much production to the video, as the group simply stands in front of a winter background, complete with giant nutcrackers. They don't need any fancy tricks or CGI though, because their vocal talents are enough to blow anyone away.

This video comes after the band released their version of "Little Drummer Boy," which is just as impressive. You can watch that below:
