When Pentatonix initially dropped their flawless cover of "Amazing Grace" [1] on Nov. 5, it immediately topped our list as one of the most beautiful renditions we've heard of the song. But during their appearance on The Kelly Clarkson [2] Show on Wednesday, the group took things to the next level with a special arrangement of the beloved tune.

Members Matt Sallee, Scott Hoying, Mitch Grassi, Kirstin Maldonado, and Kevin Olusola gave us serious chills as they delivered a stripped-down a cappella performance of "Amazing Grace — off their latest album, We Need a Little Christmas — allowing their pure vocals and stunning harmonies to take center stage. Watch their heartwarming cover in full above to get into the holiday spirit!
