On the eve of the 30th anniversary of Purple Rain, Prince has struck a deal with Warner Bros., the label that he used to be so mad at he had the word 'Slave' written on his cheek and changed his name to a glyph.

The new deal open the doors to "the release of long-awaited, previously unheard music, while giving the artist ownership of the master recordings of his classic, global hits," according to a press release.
