Rated 8/10
This is why a lot of people say they "hate" Jazz. Confusing, tuneless, random sounding...
But if you like Jazz, or even put up with it now and then, you recognize why Jazz elitists put this album at or near the top of all-time bests. It breaks every tradition while maintaining some elements. It's an intense listening experience, not casual. If you can bring yourself to really pay attention, an entirely new world of mood and feeling comes to light. Technically, the musicians are Jazz GOATs. Elvin Jones is especially incredible here, I can here some proto-Bonham during Jones' solo in "Pursuance." McCoy Tyner is also amazing, and the whole rhythm section has that magical thing that "just happens," a peak experience. Rare genius.
Then there's all of Coltrane's mysticism, which comes through in his playing. It is free, as in unconstrained. The Apple music review describes it as "an evocative play between tempo and non-tempo." A massive work of self-expression. Definitely analogous to post-modern visual art: non-linear, creates its own rules, unstructured.
This is powerful music. I can't imagine how this was created, and I've tried many times. Like Keith Jarret's live album, it's not something to listen to casually, it takes a few listens and an open mind to "get it." It's worth the effort though.
