Who Knew Piven Was Hardcore?

Jeremy Piven may play a slimy Hollywood agent on "Entourage," but underneath that pompous exterior is a rock God. Kind of.

Piven was in the crowd at a Metal Skool concert at the Key Club in Hollywood on Monday night. When the band spotted him in the crowd, they dragged him up on stage to play drums on the AC/DC classic, "Back in Black."

And he kinda rocked it! Judge for yourself.
