Sign o' the Times is the ninth studio album by the American singer, songwriter, producer, and multi-instrumentalist Prince. It was first released on March 30, 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 during 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.
