Pentatonix, A Capella Group with Beautiful Version of ‘Little Drummer Boy’ [MUSIC VIDEO]

I first came across the a capella group Pentatonix when I posted about their 'History of Music in 4 Minutes' video. They are a 5-person vocal band from Texas that combines various genres such as pop, soul, R&B, and electronic music. They were the winners of season 3 of NBC’s ‘The Sing-Off.’

Now, they have released a Christmas CD and the first song and video is just wonderful. High on a mountain top, listen to their voices blend beautifully on 'Little Drummer Boy.'
