Watching the evolution of the physical presence of Juvenile from the "Ha" video to today is like watching the evolution of his music; the scenery's changed and so have his clothes, but the gold grill and the vocal style remains, both enduring symbols of where he's come from. Mannie Fresh-produced "Power" reflects a shifting focus. New Orleans' environment is still present, but with a stronger awareness of the forces that shape it, from the personal level to the broader scope of society. Who better than Rick Ross, a totem of power in all its symbolic glory, to guest star?
