As we previously reported, the OutKast appearance marks a highly anticipated reunion for André 3000 and Big Boi, while Arcade Fire had long been rumored to be on the schedule.

They join previously announced acts The Internet, The Magician, Bombino and The Glitch Mob.

Contrary to previous years, much of this year's roster was difficult to keep under wraps. And this year's big reveal actually comes several weeks ahead of the 2013 announcement, possibly due to leaks.

This year's event is being held April 11-13 and April 18-20 in Indio, Calif.
