     Neither good nor evil exactly, he is the ultimate catalyst or kibitzer, a blue-note howl of pain and laughter such as Charlie Parker might have blown.

A kibitzer is a non-participant who hangs around a game, especially a chess match, offering advice or commentary. Many kibitzers go on to become champions. There is a 1930 film called The Kibitzer which is based on the 1929 three-act comedy play by the same name.
