With just a few weeks left to spare, hip-hop duo OutKast has finalized the track list for the long-awaited soundtrack to its film, Idlewild.

Andre 3000, Big Boi in Idlewild

The album arrives August 22, three days before the film hits theaters via Universal Pictures. The LaFace/Zomba soundtrack features guest appearances from Lil Wayne, Snoop Dogg, Sleepy Brown, and Macy Gray, among others.

The first single is "Mighty O," which was produced by Organized Noize and features OutKast principals Andre 3000 and Big Boi on the same track for the first time since 2000. The latter takes top billing on second single "Morris Brown" featuring Scar and Sleepy Brown.

In the Idlewild film, which has been postponed numerous times, Andre 3000 plays Percival, a club piano player, while Big Boi plays the club's lead performer and manager, Rooster. The film is set in the 1930s. Written and directed by music video veteran Bryan Barber, it also stars Terrence Howard, Faizon Love, and Cicely Tyson.

"This is probably the first musical that didn't have the music done before it was shot," Andre 3000 recently told Billboard. "That has been the biggest lesson I've learned in this whole thing. Next time, we'll do the music first."
