There are four "coaches, not judges" -- Cee-Lo Green, Christina Aguilera, Blake Shelton and Adam Levine. They will be forming teams of 8 contestants, whom they'll mentor. In the first round, there are blind auditions. The judges sit turned away from the stage as the contestants (who have been hand-picked for this honor) perform. If the coaches want to offer the person a chance to be on their team, the push a button that flips their chair around. If one coach turns around, the contestant is automatically on that person's team. If more than one does, the contestant gets to choose who to work with.
