About 90 acts were announced this morning (4/7), including Wilco [ tickets ], The Raconteurs [ tickets ], Love and Rockets, Gnarls Barkley [ tickets ], G. Love [ tickets ] & Special Sauce, Dierks Bentley, Blues Traveler, Bloc Party, The Black Keys, Broken Social Scene, Flogging Molly and Lupe Fiasco. The full lineup is listed below and the schedule is expected to be announced in June.

Early-bird tickets are already sold out, according to Lollapalooza's website. Advance three-day passes are currently on sale for $190 and, when those run out, regular three-day passes will go for $205. VIP packages are also available.

In addition to hosting a wide-variety of music on multiple stages, the festival will once again provide entertainment for the next generation of Lolla fans with Kidzapalooza, which includes family-oriented musicians, a hip-hop workshop, "a rock and roll petting zoo," hair and makeup styling, and a dance floor.

Lollapalooza, formerly a traveling festival, successfully reinvented itself in 2005 as a multi-day event anchored in the Windy City. Organizers later struck a deal to remain at Grant Park through 2011.

Lollapalooza 2007 sold out with an attendance of more than 167,000, and tickets for the 2008 edition are outpacing last year's, according to Billboard.
