Today would have been the legendary Prince’s 60th birthday. Not surprisingly, Prince’s estate has announced that his album, Piano & A Microphone ’83, will be released later this year.

This never-before-heard live album is a live cassette recording made solely with his piano and microphone in his home studio in Minneapolis. The album consists of nine songs including a version of “Purple Rain,” as well as a cover of “A Case of You” by Joni Mitchell. Today, Prince’s spiritual take on “Mary Don’t You Weep” was released from the album, which will also appear in the end credits of Spike Lee’s BlacKkKlansman.

Piano & A Microphone ’83 will be released on Warner Bros. on September 21st this year.
