Surprise! OutKast’s back. After rumors swirled that they were in talks to reunite, Big Boi and André 3000 have been announced as official headliners at Coachella 2014, the three-day festival taking place in April over two weekends in Indio, Calif. It’s been eight years, two Big Boi solo albums and a handful of Three Stacks guest verses since their last album ‘Idlewild,’ but the ATLiens are once again ready to make some noise. Get reacquainted with some of their greatest tracks. Reunited, and it feels so good.
