NBC today released the first promo for its American Idol rival, singing competition The Voice hosted by Carson Daly and starring music coaches Christina Aguilera, Cee-Lo Green, Adam Levine and Blake Shelton. If you were wondering how The Voice would be different from the other singing reality competition, the clip holds one clue: the coaches judge the contestants with their backs to them. As intimidating facing judges is, facing the backs of their chairs will probably make aspiring singers feel even more uncomfortable. The Voice premieres April 26.
