"You see, man, Prez has the technical anxieties of a money-making musician, he's the only one who's well dressed, see him grow worried when he blows a clinker, but the leader, that cool cat, tells him not to worry and just blow and blow--the mere sound and serious exuberance of the music is all he cares about. He's an artist. He's teaching young Prez the boxer.
