Sign o' the Times is the ninth studio album by the American singer and songwriter Prince. It was released on March 31, 1987, as a double album by Paisley Park Records and Warner Bros. Records. The album is the follow-up to Parade and is Prince's first solo album following his disbanding of the Revolution. The album's songs were largely recorded from 1986 to 1987 in sessions for releases Prince ultimately aborted: Dream Factory, the pseudonymous Camille, and finally the triple album Crystal Ball. Prince eventually compromised with label executives and shortened the length of the release to a double album. Sign o' the Times is a drastic departure from Prince's previous works, taking inspiration from social issues and spirituality. An R&B album, the album takes influence from avant-pop and hip hop, which was emerging in mainstream music. Many of the drum sounds on the album came from the Linn LM-1 drum machine, and Prince used the Fairlight CMI synthesizer to replace other instruments. Four songs contain higher-pitched vocals to represent Prince's alter ego "Camille". The album's music touches on funk, soul, psychedelic pop, electro, and rock.
