The gig itself was slightly anarchic as other musicians sat in (some uninvited but welcome) from Coltrane's Philly scene, so the final tally featured two more horn players and four percussionists (who are sadly lost in the mix). One of the more unusual aspects of this work is Coltrane vocalizing immediately after Ali's drum solo on "Leo" — it appears out of the blue almost as an introductory incantation to his tenor solo that followed! One wonders what led him to make this kind of statement, but it is definitely startling and uplifting at the same time.
While it would be easy to relegate this double CD/LP set as a collectors-only boutique item, Coltrane's mastery and the commitment to the music the other players display makes this music as worthwhile to the novice as anything released as a studio work. As a matter of fact, this is one of his better sounding live recordings. (Impulse!/Resonance)
