Lawrence Leo: #PTXThroughTheYears (6/9): 2016 Now this song is frustratingly difficult and it took me hours just to finish it. The last part ALMOST KILLED ME 💀. Kidding aside, this is one of the most creative and complicated arrangements they’ve had so far and I LOVE IT! You know what they say, Christmas wouldn’t be complete without Pentatonix. ❄️🎄 #acapellaappstore #cover #pentatonix #ptx #acapella #harmony
