Piano Guys Perform Unbelievable Rendition of ‘Angels We Have Heard On High’

This rendition of 'Angels We Have Heard On High' is unbelievable not because it's performed by multiple players on the same piano, but because of the amazing way they use more than the piano's keyboard to perform the song.

I was completely in awe just watching them play, but to hear the guys add vocals is truly amazing.
