Blue World (2019)

The album was recorded at Van Gelder Studio with the Classic Quartet in between the Crescent and A Love Supreme sessions for the film Le chat dans le sac. Director Gilles Groulx was friends with Jimmy Garrison and he used that relationship to request songs for Coltrane's quartet to record. Groulx flew to the United States to attend the recording sessions for Coltrane's only soundtrack work and Coltrane recorded it without informing his record label. After three hours in the studio, Groulx took the master tapes with him to Canada. When the director ended up shelving most of the music, it went unreleased until 2019, when Coltrane's long-time label Impulse! Records decided to release it, with the original composition "Blue World" being released on August 16, 2019 along with the announcement of the album. Release was delayed by several years due to the NFB owning the rights to the tape itself but Impulse! having the rights to release it as an album.

The recordings were stored away until the early 21st century, when an archivist from the National Film Board of Canada was tasked with assembling Groulx's work; the government agency negotiated with Impulse! to have the album released. This album comes a year after the successful release of Both Directions at Once: The Lost Album, also from Impulse!, capturing a Classic Quartet session from 1963 and is part of a trend of unreleased albums from 1950s and 1960s jazz greats released in the 2010s.
