On this past September 10th, National Public Radio’s Morning Edition program ran an intriguing feature titled: Not All “Lost” Jazz Albums Are Created Equal. It focused on several albums, either recently or about to be released, that contain previously unreleased material by iconic jazz artists like John Coltrane, Miles Davis, and Stan Getz. One of those albums was Both Directions at Once: The Lost Album, which featured material from 1963 recording sessions and reference tapes, and was released in 2018. Another is Blue World, set to be released on Impulse! Records on September 27. It features Coltrane recordings from 1964.
