"...However Coltrane was evidently sympathetic to Coleman's innovations, hence this album, recorded with Ornette's righthand man Don Cherry in 1960 and consisting for the most part of Coleman originals. This was a bit of a transitional period for Coltrane; after the tour de force that was Giant Steps and prior to the formation of the classic quartet, there's a sense that he was on the lookout for the next step, and maybe Coleman's approach suggested a new avenue to explore. That the album remained unreleased for four years suggests that Atlantic weren't entirely sure about the results, and maybe they were right. This is one of the few Coltrane sessions recorded entirely without piano (the only other I can think of is Interstellar Space), and the huge,majestic tenortone sounds a little odd in these airy, nimble surroundings."  - BBC
