Contains the (to this point) last readily available recordings of Rollins pre-Bidge sabbatical. Very revealing, in that regardless of how much he may or may not have been thrown of by Coltrane ,(and Ornette) it shows that ultimately he took the time off because, in his words, he wasn't yet "good enough".
It's humbling to think about that, and at the time it must have seemed like a perverse notion, but comparing his playing before and after, it's clear to me what he was talking about.
Still, there is some "in the zone" playing here. Not all but some. Some!
