MINNEAPOLIS (AP) — Warner Bros. Records has announced a new Prince album on what would have been the musician’s 60th birthday.

The company said Thursday that “Piano & A Microphone 1983” from Prince’s storied vault will be released on Sept. 21 on CD, vinyl and digital formats.

Warner Bros. says the album features Prince working through nine tracks in a private rehearsal recording at his now-demolished home studio in the Minneapolis suburb of Chanhassen.

Among the songs are “17 Days,” Joni Mitchell’s “A Case of You,” ″Strange Relationship,” ″International Lover” and “Purple Rain,” the title song of Prince’s 1984 hit movie.

Also included is Prince performing the spiritual “Mary Don’t You Weep.”

Prince was 57 when he died of an accidental fentanyl overdose at his Paisley Park recording complex in 2016.
