Prince - Slave Trade This film explores and documents the strange but prophetic mid-1990s period in Prince\'s career during which he took full control of his music and the way it was sold. With the help of those who witnessed the key events as they unfolded, this DVD shows that Prince is not just a remarkable musician, performer and composer, but arguably, also has the shrewdest brain in show business. The Estate of Prince Rogers Nelson is not affiliated, associated or connected with this title.
