He's all over the horn - has complete control. Do you mean he's playing out of tune? Not to my ears, although his vibrato is wide at times... No offence, but if Ornette or (early) Archie is your standard, we may hear things differently ...
Q
Thanks for your response. I shall have to consider the wide vibrato issue. As to my standard, I guess you could say Bird/Lester/Marsh/Wardell/Fats/Bud/Tristano, etc. Perhaps it's my ear. Gigi Gryce always sounds sharp to me. But that's another thread ...
