Grammy award-winning hip hop group OutKast will reunite to headline the Coachella music festival in April of this year, Pitchfork reports. The duo, composed of André 3000 and Big Boi, separated in 2007 to pursue solo careers. Big Boi went on to release the critically acclaimed album Sir Lucious Left Foot: The Son of Chico Dusty, while André 3000 went on to launch a clothing line, act in several films, and appear on tracks from the likes of Beyonce, Frank Ocean, and T.I.
