Its music video was posted on their official YouTube channel one week ago and it has already gathered over 2.4 million views. It is the follow-up to their Christmas video for "Little Drummer Boy," which was another spectacular vocal performance.
Their vocals on "Angels We Have Heard on High" are quite impressive, especially since they use their voice as their sole instrument. It starts out angelic and soothing and then they showcase their tremendous range and high notes. The control they maintain throughout the tune is astonishing. It garners an A rating.
Pentatonix were the winners of the third season of NBC's reality competition, "The Sing-Off."
