In the hip-hop world, Outkast are the epitome of album artists—give them space, and they'll fill it with something unique, experimental and layered with meaning. On "West Savannah", Big Boi spits his life story over a smooth, funky beat, while "Pink & Blue" sees André 3000 crooning atop a lonely drum loop. "13th Floor / Growing Old" finds the duo reflecting on the passage of time after a chilling sermon from Big Rube.
