Purple Rain joined his recorded music to cinema in 1984. The custom Cloud guitar made for the film became one of the recognisable instruments associated with his performances and later museum collections.

Sign o’ the Times followed a period of intense recording and the breakup of the Revolution. The estate’s discography explains how several abandoned projects fed the 1987 double album, giving fans context beyond a conventional hits list.

Purple Rain contains more than a set of studio performances. The official discography traces the title song, I Would Die 4 U and Baby I'm a Star to a benefit concert at First Avenue in Minneapolis. The recording history connects the album to a particular band and live setting.

That concert also marked guitarist Wendy Melvoin's debut with the Revolution. The band's credited members included Lisa Coleman, Bobby Z, Dr. Fink and Brown Mark. Reading these credits alongside Prince's own roles makes the collaboration visible rather than treating every recorded part as a solo performance.

Piano & A Microphone 1983 is a private home rehearsal released in 2018, not a recording of Prince's similarly named final tour. Prince sings and plays piano, with Don Batts credited as engineer. Much of the performance flows as a continuous medley.

The rehearsal includes early versions of Purple Rain and 17 Days before their 1984 releases, and Strange Relationship before its appearance on Sign o' the Times in 1987. Those differences make it useful for hearing songs in development; the year in the title refers to the recording, not its public release.
