OutKast is an American hip hop duo based out of Atlanta, Georgia formed in 1991. Their original musical style was a mixture of Dirty South and G-Funk; since then, funk, soul, electronica, and rock elements have been added to the mix. The duo is André "Andre 3000" Benjamin (formerly known as "Dre") and Antwan "Big Boi" Patton, both from the Atlanta area. They are also a part of the Atlanta based music collective called the Dungeon Family (Organized Noize, Goodie Mob, Cool Breeze, Witchdoctor, Joi, Slimm Calhoun, and more).
