"The Sing-Off" will feature a cappella groups performing popular songs from various genres, arranged and sung like you've never heard before. There is no lip-synching, back-up band or safety net. Ultimately, America will decide the winning group.

During last season, the four December telecasts of "The Sing-Off" averaged a 2.5 rating, 7 share in adults 18-49 and 7.3 million viewers overall. The December 21 finale attracted NBC's biggest overall viewership in the time period in more than three months.

Returning celebrity judges Ben Folds who recently released the CD "Lonely Avenue," a collaboration with novelist Nick Hornby, Shawn Stockman and Nicole Scherzinger will critique each performance, narrowing down the finalists to the top three groups competing for America's vote.

Returning for a special performance will be Nota, the winner of the show's freshman season in 2009.

In conjunction with the second season of "The Sing-Off," Epic Records will be releasing digital tracks of each group's performance immediately following the airing of each episode. All 10 competing groups from the upcoming season will also be featured on "The Sing-Off: Harmonies for the Holidays" being released by Epic Records on November 30.

Nota has distinguished itself among a cappella groups with its fusion of various musical styles evident in its self-titled debut album, to be released in November 2, 2010. They are currently wrapping up Shakira's Sale el Sol U.S. tour where they performed as the opening act to rave reviews and incredible reactions. Their album includes R&B and pop influences blended with Latin rhythms like mereingue, bachata, and samba, which create a sound that is unique and original. The sextet takes a new approach to familiar songs, covering "I Gotta Feeling," "Down," "I Need to Know" and "My Girl," as well as original songs written by the group."

"The Sing-Off" is produced by Tenth Planet Productions, Outlaw Productions and Sony Pictures Television. Joel Gallen, Deb Newmyer and Sam Weisman are executive producers. Josh Greenberg serves as co-executive producer.
