Kid Cudi, Childish Gambino and Raury have been added to Outkast's homecoming show at Atlanta's Centennial Olympic Park on Sept. 27. Dubbed #ATLast, the concert is being curated by the reunited duo, who promise additional performers at the one-day fest in downtown Atlanta.

"Dream come true opening for Outkast, holy fu-k lets go!" Kid Cudi said Wednesday morning on Twitter.

Tickets and more information can be found on Outkast's new website, outkastatlast.com.

"It's only right that we give the hometown what we've been giving the rest of the world, Atliens in ATL, homecoming! Festival Killers," said Big Boi in a previous statement. "We want to say thank you" to Atlanta, Andre 3000 added.

The duo confirmed in January plans for an international headlining festival tour that began at the Coachella Valley Music and Arts Fest and included more than 40 dates throughout the summer. Outkast's tour came close to home when the pair played the CounterPoint Music & Arts Festival in April, a three-day event in Rome, Ga., about 60 miles northwest of downtown Atlanta.
