[Official Video] Mary, Did You Know? - Pentatonix
Pentatonix gets in the Christmas spirit with "Mary, Did You Know?" off of their latest Christmas album That's Christmas To Me. The season 3 Sing Off winners dominated on the NBC a cappella singing competition week to week, and now they've taken over the internet and have breathed new life back into a cappella music. Be sure to pick up their latest studio album PTX Vol. 3, as well as their Christmas album. Don't forget to look out for them in Pitch Perfect 2 next summer!
