“Mary Don’t You Weep,” is from Piano and a Microphone 1983, a forthcoming Prince album of previously unreleased home recordings set for release on Sept. 21. The album’s nine tracks are from cassette recordings Prince made at his home studio in Chanhassen, Minnesota. The track, a 19th century spiritual, is also included in the end credits of Spike Lee’s new film, BlacKkKlansman, which premiered at Cannes in May.
