I once heard a black man playing sax on Fifth Ave. in Midtown of New York City. Basically it was a neverending blues with a lot of improvising. Technically he was quite good though not great. But the music that was coming out of him was incredible - dark, poweful, intense and sophisticated. Very deep. It was late evening, not many people there, I was in fact the only one who was standing there for twenty minutes or so and listening. He kept playing, maybe for hours, and could be heard from far away. Great talent.
