Impulse! announced details of previously unreleased John Coltrane recording. Coltrane recorded this session on 24 June 1964 - between Crescent and A Love Supreme. Originally, it was supposed to be included on the soundtrack to the film "Le chat dans le sac", but most of the material was shelved until today. The recordings of the classic The John Coltrane Quartet line-up (Coltrane, Jimmy Garrison, Elvin Jones, McCoy Tyner) will be released on 27 September as "Blue World" album.
