"There is never any end," John Coltrane said sometime in the mid-1960s, at the height of his powers. "There are always new sounds to imagine; new feelings to get at." Coltrane, one of jazz's most revered saxophonists, was speaking to Nat Hentoff about an eternal quest — a compulsion to reach toward the next horizon, and the next.

More than half a century after his death, that restless pronouncement also carries implications for us, the beneficiaries of Coltrane's music. Not only because his body of work represents a fathomless realm of insight, as his many admirers can attest — but also because it has recently yielded surprise discoveries from his prime.

Just over a year ago, Impulse! had a phenomenal success with Both Directions at Once: The Lost Album, a startling assemblage of studio recordings made by the John Coltrane Quartet in 1963. That two-disc set posthumously gave Coltrane his first-ever debut on the Billboard 200, at No. 21; according to the label, global sales have exceeded 250,000 copies.

Now comes word of another new album by the classic John Coltrane Quartet, with McCoy Tyner on piano, Jimmy Garrison on bass and Elvin Jones on drums. Blue World will be released on Impulse!/UMe on Sept. 27, and like Both Directions it offers an unexpected view on a pivotal period in the band's evolution. It was recorded at Van Gelder Studios on June 24, 1964 — a few weeks after the quartet put a finishing touch on the album Crescent — as the soundtrack to a Canadian art film. Because the date had gone unnoted in session recording logs, this music has occupied a blind spot for Trane-ologists, archivists and historians.
