Sara Bareilles

Bareilles, a three-time Grammy Award nominee, released her platinum-selling major label debut "Little Voice" in 2007. The album's first single, "Love Song," was a hit in 22 countries, including the Billboard Hot 100. It garnered a Grammy nomination for the prestigious Song of the Year before going multi-platinum. No stranger to a cappella music, Bareilles was part of the group Awaken A Cappella at UCLA.

First Day on the Job

It was pretty surreal taking the stage for the first time at The Sing-Off. I came into this position as a big fan of the show, but really had no way of knowing what it would feel like to sit behind the judges' desk and actually take it all in. As the show started, my stomach was in knots, and I was really nervous about when it would be my turn to talk. Sounds silly, but it's true. What if I use the work "like" too many times? What if there's spinach in my teeth? What if I say something stupid? What if I swear? (Turns out that last one's not really a problem. Thanks NBC!) And then eight of our 16 groups took the stage and did the opening number - Pink's "F-in Perfect."
