We’ve seen Cee Lo Green join Motley Crue on stage for a mash up of his hit “Fuck You” and “Don’t Go Away Mad.” But it looks like Mr. Green’s knowledge of metal doesn’t stop at 80’s hair rock.

During his set at Lollapalooza August 6 in Chicago, the R&B singer/The Voice judge performed a cover of Danzig’s “Mother.” That’s right, Cee Lo Green covered “Mother.” And much to our surprise…it sounds pretty decent. It’s not the most amazing cover, and it’s still a bit of a shocker to hear Cee Lo Green and Danzig in the same sentence, but he’s got the voice (no pun intended) to pull it off.

And thanks to YouTube, video of the cover can be seen above.
