Modest Mouse, LCD Soundsystem and a reunited Pavement head the initial lineup unveiled by organizers of the 2010 Pitchfork Music Festival.

The three-day outdoor event, which will take place June 16-18 at Chicago's Union Park, will also feature hip-hop star Raekwon (of the Wu-Tang Clan) and singer/songwriters St. Vincent and Cass McCombs, among others. A complete list of currently confirmed performers is available at the event's website.

Tickets for the festival are currently on sale, with prices ranging from $40 for single-day tickets to $90 for a three-day pass.

Lo-fi progenitors Pavement announced earlier this year that they would reunite for a world tour, including a full slate of European and Far East dates, along with an April 18 slot at Southern California's Coachella Festival. The comeback bid is intended to hold for this year only, and is "not a prelude to additional jaunts and/or a permanent reunion," according to the band's website.

The California group, which debuted with 1992's "Slanted and Enchanted," made its last live appearance in late 1999, formally breaking up the following year. A new 23-track compilation album, "Quarantine The Past: The Best Of Pavement," is due March 9 on the band's longtime label, Matador. The retrospective will be available in CD, double-vinyl LP and digital formats.

Now in its fifth year of existence, the Pitchfork Music Festival began in 2006, drawing an estimated 35,000 fans to Union Park for a two-day event that featured Spoon, Yo La Tengo, Ted Leo and the Pharmacists, and The Futureheads.
