Superfly, released in 1972 and one of the first concept albums in soul music, met immediate and astounding commercial success. The album was intended as a soundtrack to the film Superfly yet was a rare circumstance where the soundtrack received far more attention than it's respective film. One of the defining aspects of Superfly was that the album exemplified fantastic depth both lyrically and musically. Superfly's lyrics follow socially critical themes, telling it straight about the hard life in the inner-city for a black man in the 1970s, which was uncommon in popular music at the time. Musically, the album features complex percussive rhythms, captivating bass grooves, and some of the best sounds in funk music.
