OutKast set dates for album and movie

OutKast have finally announced release dates for their film Idlewild and its soundtrack, LaFace.

The album will launch on August 22 then the movie – set in the 1930s – three days later.

'Mighty O', slated as the first single from the record, was leaked last week. It is reportedly based around a famous scatting sample from Cab Calloway's 'Minnie the Moocher'.

The music will be fitting for a movie about running a speakeasy, OutKast said, but still in the band's usual style. "It's hip-hop. It's OutKast," Big Boi said last year. "It is what we've been doing for years. Some songs have a little more piano or whatever, but the whole project was a natural progression from a double CD."

It also features acts including Macy Gray and Patti LaBelle.
