The Voice Season 1 Coaches' 1st-Ever Group Performance Is Beyond Electric

Blake Shelton, Christina Aguilera, Adam Levine, and CeeLo Green kicked the show off with an epic collab. 

By Jackie Manno

When The Voice burst onto the scene in 2011, OG Coaches Adam Levine, Christina Aguilera, Blake Shelton, and CeeLo Green joined forces for a rendition of Green's hit ''Crazy" (when he was in the duo known as Gnarls Barkley). 

How to Watch

Watch The Voice Mondays and Tuesdays at 8/7c on NBC and next day on Peacock. 

During their cover, Levine handled the introduction lyrics while the other Coaches hummed backup vocals. The crowd then went wild when Shelton started singing and Levine kicked in with the drums. Naturally, X-Tina riffed away while Shelton played his guitar with confidence.

''Crazy'' by Gnarls Barkley lyrics

I remember when
I remember, I remember when I lost my mind
There was something so pleasant about that place
Even your emotions have an echo in so much space

And when you're out there without care
Yeah, I was out of touch
But it wasn't because I didn't know enough
I just knew too much

Does that make me crazy?
Does that make me crazy?
Does that make me crazy?

And I hope that you are having the time of your life
But think twice, that's my only advice
Come on now, who do you, who do you, who do you
Who do you think you are
Ha ha ha, bless your soul
You really think you're in control

I think you're crazy
I think you're crazy
I think you're crazy
Just like me

My heroes had the heart to lose their lives out on the limb
And all I remember is thinking I want to be like them

Ever since I was little
Ever since I was little it looked like fun
And it's no coincidence I've come
And I can die when I'm done

But maybe I'm crazy
Maybe you're crazy
Maybe we're crazy
