content: I've listened to a lot of Coltrane's stuff, and I'd say this is one of the worst albums. Om is a good track, but Ascention is simply abyssmal. I read somewhere that the musicians were on acid when the recording was made and it shows. 40+ minutes of pure agony, twice. If you're looking for essential Coltrane, this is not the place to start. I put "Crescent," "A Love Supreme," and the "The Complete 1961 Village Vanguard Recordings" at the top of my list, and this one at the bottom. This album is purely for those interested in knowing what a great musician sounds like when he lets go completely.
