Season 1
The Sing-Off is a unique competition series that sings a different tune and is hosted by multi-platinum recording artist Nick Lachey.
The show scours America in search of the best a cappella groups, ranging in various sizes and ages. In Season 3 the competition expanded to the 16 very best groups, who perform popular songs in weekly competitions, which culminate with a live finale revealing the grand-prize winner.
The groups compete for America's vote and a chance to walk away with the ultimate prize - a Sony Music recording contract and $200,000.
There's no lip-synching, back-up bands or safety net. One group is eliminated every week during this one-of-a-kind battle of voices that leads up to a live finale - where viewers decide the winner.
The celebrity judges who critique the singing groups using their musical expertise are Ben Folds (Ben Folds Five), Shawn Stockman (Boyz II Men) and Jewel. Nicole Scherzinger (Pussycat Dolls) was a judge for the first two seasons before being replaced by Sara Bareilles (Love Song and King of Anything), after she left the show to be a judge on The X Factor. Bareilles left after one season and was replaced by Jewel.
The Sing-Off is produced by Joel Gallen's (America's Best Dance Crew) Tenth Planet Productions, Outlaw Entertainment and Sony Pictures Television. Gallen, Deb Newmyer (The Ugly Truth), Sam Weisman (George of the Jungle) and Josh Greenberg (America's Best Dance Crew) are executive producers.
