You can stop spinning the Lollapalooza wheel of fortune, as the official lineup has been announced for the 2010 fest at Chicago’s Grant Park. The three-day event will take place August 6 – 8, and for it Soundgarden will reunite for their first performance in 13 years, Lady Gaga will bring the glam and glitter, Erykah Badu will keep her clothes on (maybe?) and Green Day will rock out with jams from their Grammy-winning repertoire.

Head below to see the full Lollapalooza lineup, courtesy of our friends at Stereogum.

Festival creator Perry Farrell spoke to Rolling Stone about the inclusion of Lady Gaga—who performed at Lollapalooza on a smaller stage in 2007—as a headliner:

“Lady Gaga represents to me the music industry today. She’s a good representation of where it’s at and where everybody’s trying to get to. If you look at the Grammys, it looked like everybody was trying to catch up to Lady Gaga. We just see the vision of Lady Gaga in Chicago in Grant Park surrounded by all those beautiful buildings—we all just thought that it would be an epic performance… She had a real interest in doing it as well because she felt like we had given her a break to go into the world of legitimate music, you know not just pop.”

Gaga’s appearance will fall right between the Kansas City and Los Angeles concert dates for her summer arena tour. But will her third album be out by then?
