No one sounds like OutKast. While every underground crew with dirty beats and gruff rhymes might claim to be reinventing hiphop, the Atlanta duo are the only group in the music who are making something truly original.
Not that there aren't recognizable reference points. Stankonia includes snippets of Miami bass and slinky Dirty South beats, but it's all run through OutKast's decidedly P-Funk-influenced filter, where everything comes out in reverse and anything is possible in the name of hiphop. Walls of trombones, gospel choirs, stuttering rhythms and two-step breakbeats back up Andre 3000 and Big Boi's rapid-fire, introspective rhymes. It's all eerily familiar but also sounds like it's from Mars, and hiphop is better for it.
