Prince’s vault of unreleased music is being shopped to the major labels for upwards of $35 million according to Billboard. The vault is Prince’s legendary archive of music that was never released during his lifetime. The Revolution has already revealed the existence of an album they recorded in the ’80’s that was shelved. Estate advisors L. Londell McMillan and Charles Koppelman are negotiating the sale of the music that has intrigued Prince fans for years because of its unknown contents. Warner Brothers is planning to release a deluxe version of Purple Rain and a new greatest hits collection in the near future. Prince’s death in April without a will left a lotÂ of organizational work for his estate managers and they are currently waiting for the Minneapolis City Council to give them a permit so that tours of Paisley Park can resume.
