After numerous delays, the OutKast film Idlewild is now slated to arrive August 25 in theaters, three days after the release of its soundtrack.

Andre 3000, Big Boi in Idlewild

The first single from the LaFace album, "Mighty O," leaked online earlier this week. The cut features OutKast's take on Cab Calloway's famous scatting from "Minnie the Moocher."

Andre 3000's verse finds him resisting easy categorization: "The damsels in distress but they a mess / They only like my armor and that I'm a performer/ They read one magazine and want to think they're getting warmer / They're only getting colder."

Big Boi, meanwhile, reasserts his dominance over other rappers with lines like "Intended for anyone filling out this application / An estimate is needed for your underestimation / I'm firing on the spot, go back and check your calculations."

Written and directed by Bryan Barber, Idlewild is set in the 1930s around the music and business of running a speakeasy. While it will fit the film's context, Big Boi told Billboard.com last year not to expect period music.

"It's hip-hop. It's OutKast. It is what we've been doing for years," he said. "Some songs have a little more piano or whatever, but the whole project was a natural progression from a double CD (OutKast's 2003 album Speakerboxx/The Love Below). It was like, where do we go from here?"

Recording artists Patti LaBelle, Macy Gray, and Fishbone's Angelo Moore also appear in Idlewild, along with actors Terrence Howard, Faizon Love, Ben Vereen, and Cicely Tyson, among others.
