Hip-hop duo OutKast will reunite for the first time since their last album eight years ago to headline this year's Coachella Valley Music and Arts Festival, organizers said. Canadian-American rock band Arcade Fire and British rockers Muse will headline the other dates of the festival in the Southern California desert town of Indio, organizers said in a post on Twitter late on Wednesday. The annual music festival, set for two consecutive weekends in April over a total of six days, has become one of the largest U.S. music festivals, attracting more than 80,000 people, including many Hollywood celebrities. Grammy-winning OutKast, which consists of Atlanta rappers Andre 3000 (Andre Benjamin) and Big Boi (Antwan Patton), last released the album "Idlewild" together in 2006.
