A previously unheard home studio cassette recording of Prince performing at his piano in 1983 will be released as Piano & A Microphone on September 21.
The nine-track, 35-minute project from the Prince Estate in coordination with Warner Bros. Records is planned for what would have been the rock icon's 60th birthday.
It is available to pre-order on CD, LP, deluxe CD+LP, digital release and pre-save for streaming.
The album cover features a rare image of Prince backstage during the 1999 tour.
The Deluxe version will include a 12 inch booklet with never-before-seen candid photos of the singer.
