'The Sing-Off' premiered in 2009 as a five-night event hosted by multi-platinum recording artist Nick Lachey.

The celebrity judges who critique the singing groups with their expertise are Ben Folds (Ben Folds Five), Jewel and Shawn Stockman (Boyz II Men).

The program showcases the country’s Top Ten a cappella groups performing popular songs like viewers have never heard them before. There’s no lip-synching, back-up bands or safety net.

The performers sing for America’s vote and for the ultimate prize – a Sony Music recording contract and $100,000.
