Bluesy Brits Gomez and San Francisco space-garage trio Black Rebel Motorcycle Club have been added to the bill, which also includes Morrissey, The String Cheese Incident, The Flaming Lips, Sonic Youth, Modest Mouse, and The Polyphonic Spree.

Founder Perry Farrell has been issuing a series of impassioned statements on the revamped Lollapalooza, which is billed as the first-ever two-day music festival on wheels.

“The spirit I envision to come over the country with the 2004 Lolla is akin to the gypsy of old,” Farrell said. “But his coach is solar-powered in keeping with the music’s message. He’s part of the revolution-solution, having a little fun as a political prankster.”

A full lineup and itinerary are expected soon.
