'Entourage's' Jeremy Piven rocks out at The Roxy: Huh?

Earlier this week, "Entourage" star Jeremy Piven, 45, showed up at The Roxy Theatre in Los Angeles and apparently jammed with the Street Drum Corps, who LA Weekly calls their "favorite band of misfit drummers."

We're not sure where Piven fits in with the group and we're not sure he does, but check out "Peter Pan" being all rock and roll-ish.
