 At first the band was used sparsely in the studio, but this gradually changed during 1983.According to his former manager Bob Cavallo, in the early 1980s Prince required his management to obtain a deal for him to star in a major motion picture, despite the fact that his exposure at that point was limited to several pop and R&B hits, music videos and occasional TV performances.This resulted in the hit film "Purple Rain" (1984), which starred Prince and was loosely autobiographical, and the eponymous studio album, which was also the soundtrack to the film.
