Earlier this summer, we announced Hip-Hop duo Outkast would be holding a major concert in their hometown Atlanta, GA in celebration of the 20th anniversary year of their debut album SouthernPlaylistCadaliacMuzik. Outkast #ATLast, was originally set for Friday, September 26th at Centennial Olympic Park in heart of downtown Atlanta. After selling out of tickets in less than one hour, the group added a second show for Saturday, but that still wasn't enough for fellow Atliens. The group added a third show, officially turning Atlanta into Outkast weekend! Yesterday, the group confirmed the feature artist that will be joining them during this weekend's shows.
