That was a hell of a set, maybe better than any Blue Note jam session with Smith -- one of the best examples I can recall of Chuck's sense of how to assemble just the right guys. I thought the drummer was Mickey Roker, but clearly I'm wrong there.
Early Hardman had a certain stiffness (as in the title of that Jazz Messengers tune "Stanley's Stiff Chickens") and thinness of tone that was, if you dug him, inseparable from what made him so good. In effect, he really didn't have that many licks, if any, though it sounded as though he might; he was just trying to keep the line moving forward at all costs -- just a very serious honest player. Later on, as he became a better player of the instrument, he just got better and better overall.
I am a fan of the Messengers that featured Hardman, McLean, Dockery and De Brest and have most of their recordings. Bill's work is exactly as Larry describes under "early Hardman", and there was a fierceness in his playing which was entirely in keeping with the character of this group as a whole.
