Modest Mouse

The initial lineup for the 39th annual Bumbershoot Music & Arts Festival has been announced, along with the promise that there's "much more to come."

Sheryl Crow, Modest Mouse, Katy Perry, and Michael Franti & Spearhead lead off the lineup, which also includes MSTRKRFT, Matt & Kim, Holy F**k, the Long Winters, No Age, Entourage star Adrian Grenier's group the Honey Brothers, and Natalie Portman's Shaved Head.

The festival, set to return to the Seattle Center over Labor Day Weekend (September 5–7), will also showcase other aspects of the arts -- including visual exhibitions featuring work from Paul Miller (a.k.a. DJ Spooky, who is also performing), a poster show, and performances from the Pacific Northwest Ballet.

Three-day passes are on sale now ($80) through the festival's official website, with single-day tickets to go on sale at a later date. Check out the complete lineup (thus far) below, and leave your thoughts in the comment section.
