Crystal Ball by Prince
Crystal Ball is a four-disc box set by American recording artist Prince. It contains three compilation albums of "previously bootlegged" material, along with The Truth, a bonus disc of 12 new acoustic songs. Internet pre-orders included an instrumental album, Kamasutra. Prince once planned to release a 3-LP album around 1986, also called Crystal Ball. That album was edited down to a 2-LP and renamed Sign "O" the Times. Its title track became the title track for this compilation, 10 years later.
