Red Hot Chili Peppers Rock Out With Eddie Vedder

The Red Hot Chili Peppers were joined onstage by Pearl Jam frontman Eddie Vedder Saturday night during a benefit concert in L.A.

Vedder jumped onstage during the band’s encore for covers of “Purple Rain” and “All Along The Watchtower”, capping off a fundraiser for the Silverlake Conservatory.

Vedder also covered Tom Petty’s “Wildflowers” during a solo set earlier in the evening.

What’s the coolest ‘guest star’ you’ve ever seen during a concert? Most unexpected cover song?
