It is a bit difficult to pinpoint OutKast's calling card. This is because OutKast has never been afraid to mix things up. Each of their albums has seen them take things in an entirely new direction. In this sense, OutKast's calling card could be a willingness to change. André and Big Boi never want their music to sound stale. As André explained to Rolling Stone, "It's the people who take whatever music they doing so far to the left of what was going on. Put on any album from goddamned 1966 and put on a Sly Stone album - it sounds very different - P-Funk from any time sounds different. Those are the people that inspired us to blow n----s' minds." So OutKast's calling card could be a determination to continually blow minds - whether through their music or through André's insane fashion sense. Certainly when they first hit the music scene, OutKast's calling card was their more traditional brand of Southern hip-hop, with its slow beat and drawling delivery. Then they showed off their funk and soul sides with an album like Stankonia. Today, it could be argued that their calling card is the song "Hey Ya!" off their 2003 double-album, Speakerboxxx/The Love Below, which was one of those rare songs that appeared on hip-hop, rock and pop radio stations all at once.
