There isn't much more the four coaches can do to show just how much they can offer the performers who join their team, but show them why they have earned their spots on "The Voice" in the first place.
We're so excited to share this preview of pop singer Christina Aguilera, country artist Blake Shelton, and Maroon 5's Adam Levine joining funk singer Cee Lo Green on his hit song, "Crazy."

"The Voice" premieres Tuesday, April 26 at 9 p.m. ET on NBC.
Will you be tuning into "The Voice"?
