The lineup for July 17 features previously announced acts Morrissey, Sonic Youth, Modest Mouse, Le Tigre and Black Rebel Motorcycle Club as well as new additions The Von Bondies, Broken Social Scene, The Walkmen, Wolf Eyes, Danger Mouse, The Datsuns, Bumblebeez 81 and more.

The String Cheese Incident, The Flaming Lips, Gomez, and The Polyphonic Spree top the bill on July 18. They’ll be joined by The Thrills, The Coup, Sound Tribe Sector 9, Elbow, Wheat and others.

Both days will feature the “organic electro-dub-breakbeat grooviness” of DJ Peretz, a.k.a. Lollapalooza founder/guiding force Perry Farrell.

The traveling festival will kick off July 14-15 near Seattle at Auburn, Wash.’s White River Amphitheatre. Although most of the newly announced acts are confirmed only for San Francisco, you can bet most of them will be coming along for more Lolla dates.

As promised, ticket prices are lower this year – $29.50 per day for general admission and $49.50 for reserved seating, with special two-day general admission passes going for $50.
