Prior to the disbanding of the Revolution, Prince was working on two separate projects, the Revolution album "Dream Factory" and a solo effort, "Camille". Unlike the three previous band albums, "Dream Factory" included input from the band members and featured songs with lead vocals by Wendy & Lisa. The "Camille" project saw Prince create a new androgynous persona primarily singing in a sped-up, female-sounding voice. With the dismissal of the Revolution, Prince consolidated material from both shelved albums, along with some new songs, into a three-LP album to be titled "Crystal Ball". Warner Bros. forced Prince to trim the triple album to a double album, and "Sign o' the Times" was released on March 31, 1987.
