On March 6, 1963, the John Coltrane Quartet played a session at the famed Van Gelder Studios in Englewood Cliffs, New Jersey. They recorded for approximately five hours—they had a show at Birdland in midtown Manhattan to get to later that evening. The tape was never released and was thought to be lost after Coltrane’s record label, Impulse!, was bought by ABC Records, and the archives were purged. But a mono copy tape that Coltrane took home from the session recently resurfaced, and the results are being touted as a lost Coltrane album.
