Iggy Pop and the Stooges heated up the North Stage up just as it was cooling down outside. Iggy, classically shirtless, rebellious and potty-mouthed, was begging security to let crowd surfing fans on stage.

When they refrained, he came off the stage himself to greet them. He addressed the mob as Baltimore, D.C., and the "surrounding puddles of weirdness" before he launched into a set list comprised of classic tunes like "I Got a Right" and "Little Electric Chair."

It was definitely one of the most energetic and classically rock and roll shows of the festival on the North Stage (yesterday's headliners on that stage were much more mellow Wilco and Jack Johnson) and it left the crowd is more than warmed up for Stone Temple Pilots and Nine Inch Nails.
