Slave Trade: How Prince Re-Made the Music Business is a 2014 English-language Documentary movie. In the mid-1990s reports emerged that Prince had fallen into dispute with his record company. Having signed what was ostensibly a new 100 million dollar contract just a couple of years before, Prince was now demanding - not unreasonably to most commentators - control of his masters and the freedom to release what he wanted when he wanted. Slave trade: how prince re-made the music business stars Prince, Michael Bland, Sonny Thompson, Alan Leeds, Marva King and Thomas Arnold. It was released on 8th July 2014.
