The Sing-Off

The Sing-Off is a Canadian competition-programma which aired on NBC. The series premiered on December 14, 2009.

"The Sing-Off" is a one-of-a-kind battle of voices that features the country's top a cappella groups performing popular songs in a way that viewers never heard them before. There's no lip-synching, back-up bands or safety net. They'll be singing for America's vote with the winner walking away with the ultimate prize -- an Epic Records/Sony Music recording contract.
