The Sing Off type TV Show

Brace yourselves, a-caholics! EW has confirmed that NBC is bringing back its a cappella competition The Sing-Off for a fourth season.

“I am happily able to confirm that casting is going on. The show is back!” producer Deke Sharon tells EW over the phone. A casting call site went live today, and Sharon says that, within minutes, there were already group registrations pouring in.

The Sing-Off was never officially canceled after its super-sized third season, which earned lackluster ratings in fall 2011, but NBC passed on picking it up for a fourth go-round in 2012. Still, in the time that has transpired, a cappella’s popularity has surged. The Sing-Off‘s Season 3 winners, Pentatonix, have become viral staples with their inventive covers and originals, and the huge success of Pitch Perfect (for which Deke Sharon arranged the music) has breathed new energy into the genre.

Mark Burnett Productions has come aboard to work on Season 4 (how’s that for synergy with The Voice?), and the upcoming season’s structure is expected to return to the holiday format used in Seasons 1 and 2. As far as judging and hosting duties, nothing is official just yet.

So get ready for more percussive syllables, bright-colored cardigans, smart judging, and (fingers crossed!) amazing Nick Lachey puns coming your way later this year. Oh yeah, plus some incredible vocal displays like this, too:
