Last year we got “Both Directions at Once,” an album culled from previously unheard studio recordings that John Coltrane made in 1963 with his classic quartet. On Sept. 27, Impulse! will release “Blue World,” another collection of tracks that — like the “Both Directions” material — the group recorded in one day at Rudy Van Gelder’s famed studio, and Coltrane never seems to have thought of much again. This time the year was 1964, and the group was making the soundtrack for a Canadian new-wave film, “Le Chat dans le Sac.”

The first single available from “Blue World” is its title track: a modal, one-chord retrofit of the Harold Arlen-Johnny Mercer standard “Out of This World,” which Coltrane retitled here, almost certainly for copyright reasons. (This was an independent session, conducted without the involvement of Impulse! or its executive, Bob Thiele, who typically produced Coltrane’s albums during this period.)
