Sign o' the Times is Prince's ninth studio album that was released on March 31, 1987 by Warner Bros. Records & Paisley Park Records.
It was Prince's first album following the disbandment of his backing band, The Revolution.
Initially intending to release a triple album culled from these sessions, Prince compromised with label executives and shortened the length of the release to a double album.
The album's music contains a varied range of styles including funk, soul, psychedelic pop, electro and rock music.
It became Prince's most acclaimed record and was ranked by several publications as one of the greatest albums ever.
Its release was supported by several singles in addition to a well-received concert film "Sign o' the Times" of the same name.
