As OutKast near the end of their glorious, festival-headlining tour, they're making sure to stop by one of the biggest parks in their hometown for a proper send-off before their reunion jaunt is officially over. They're doing so in style, too, and bringing a star-studded support roster to Atlanta's Centennial Olympic Park to celebrate.

Janelle MonáeChildish GambinoSolange2 ChainzB.o.B.Killer MikeKid Cudi, Raury and more will be joining Big Boi and André 3000 onstage as supporting acts in Atlanta September 26-28. 

Janelle, Solange and 2 Chainz will shake it like a Polaroid picture (and hopefully get in on a massive sing-along during "Hey Ya!") on Friday. Saturday will see sets from Childish Gambino, Kid Cudi and Raury. Sunday is one giant hip hop love fest with the likes of Killer Mike, 8Ball and MJG, Bun B, K Camp, Devin the Dude, Kilo, Gipp Goodie and DJ Unk. We knew OutKast would go HARD at home, and they're taking the lineup of these Atlanta shows pretty seriously with this intense array of talent.

After Atlanta, OutKast will head to Vegas' Life is Beautiful Festival, then Treasure Island and close out festival season with a set at the Voodoo Music Experience Halloween weekend.
