Film which explores how Prince — showman, artist, enigma — revolutionised the perception of black music in the 1980s with worldwide hits such as 1999, Kiss, Raspberry Beret and Alphabet Street. He became a global sensation with the release of the Oscar-winning, semi-autobiographical movie Purple Rain in 1984, embarking on an incredible journey of musical self-discovery that continued right up to his passing in April 2016, aged 57. From the psychedelic Around the World in a Day to his masterpiece album Sign O' the Times and experiments with hip-hop and jazz, Prince was one of most ambitious and prolific songwriters of his generation. He tested the boundaries of taste and decency with explicit sexual lyrics and stage shows during his early career, and in the 1990s fought for ownership of his name and control of his music, played out in a public battle with his former label, Warner. Highly regarded as one of the most flamboyant live performers ever, Prince was a controversial and famously elusive creative force. Contributors include Revolution guitarist Dez Dickerson, Paisley Park label president Alan Leeds, hip-hop legend Chuck D and Prince "Mastermind" and UK soul star Beverley Knight.
