The Prince Estate, in partnership with Warner Bros. Records, release Piano & A Microphone 1983 album, a nine track, 35-minute album featuring a previously unreleased home studio cassette recording of Prince at his piano. The private rehearsal provides a rare, intimate glimpse into Prince’s creative process as he worked through songs which include 17 Days and Purple Rain (neither of which would be released until 1984), a cover of Joni Mitchell’s A Case Of You, Strange Relationship (not released until 1987 on his critically acclaimed Sign O’ The Times album), and International Lover.
