One of the world's best a capella groups, Pentatonix
, released their massively successful holiday album and only ET's Brooke Anderson was behind the scenes
for the making of their original Christmas video.
After winning NBC's The Sing-Off competition in 2011, Scott Hoying, Mitch Grassi, Kirstie Maldonado, Avi Kaplan and Kevin Olusola sky rocketed to fame and then got to work spending an immense amount of time recording in the studio and performing in arenas.
All that hard work has clearly paid off as their holiday album, That's Christmas to Me, has gone platinum and surpassed Beyonce to become the fourth best-selling album of 2014. The group also received their first GRAMMY nomination for Best Arrangement, Instrumental or A Capella for their Daft Punk melody.
And if they weren't hot enough, they were asked to perform on The Kennedy Center Honors, airing Dec. 30 on CBS, where they sang "That Thing You Do" for honoree Tom Hanks. And the icing on the cake for their huge year -- they linked up with the ultimate a capella movie, landing a part in Pitch Perfect 2.
"It kind of came about all of a sudden," said Hoying. "They called us and they just wanted us to be in the movie. We didn't know what it was, and then we got there and it was like a crazy set, all these famous people like Anna Kendrick walking by and Rebel Wilson. It was just so fast and it was crazy. It all happened in one day."
Like any group, they can sometimes get into small tiffs, one thing they all seemed to agree on was their favorite song off their popular holiday album.
"My personal favorite is 'That's Christmas to Me'," said Olusola, receiving nods from the rest of the group. "I think it's very personal to us. The feeling of nostalgia of what Christmas means is so inherent in the song."
And they certainly captured that spirit in their video!
