NBC's A cappella talent competition 'The Sing-Off' returns for a new season tonight at 9PM ET. Host Nick Lachey made an appearance on 'Today' (9AM ET on NBC) to talk about the judging changes the show has made this season, and the inspiring musical atmosphere the show fosters. It's so contagious that Lachey has been working in the studio on a new project of his own.
'The Sing-Off' will have a new judges this year, as Sara Bareilles joins Ben Folds and rest of the crew. It will also have a longer season, as its moving to 16 episodes. Lachey said the new judges bring a wealth of energy, and experience, to a set that's already brimming with its own unique vibe. The show has struck such a nerve that not only is it creating A cappella groups as part of the competition, but singers are starting to form their own groups to compete for a spot in the competition.
