The a capella singing competition returns for a second season. Ten groups are competing for a recording contract. The groups perform songs from a variety of genres, with no backup band to help them along the way. Nick Lachey, formerly a member of 98 Degrees, returns as host.

Holiday songs are performed by winning groups from each season, an ensemble of lead singers from Season 3 and special guests.
