There is a gesture he has, a motion, that always reminds me of a great batter leaning into a hit. He has a way of throwing one foot forward, putting his head down a bit as he silently runs the valves, and then the cheeks bloom out in the way that has mystified his dentist for years, and he hits into the solo. When that foot goes forward like that, you know that John Birks Gillespie is no longer clowning. Stand back.
