I like Joe Pass because he always has such taste. You know that he could do whatever he wants to do on the guitar, but he holds himself back just a bit, restrains himself from showing off too much.
When I was a teenager I worked on a play as a stage manager with a very good professional older cast who I looked up to. I remember one actor, Gene, who came off stage into the wings where I was, after playing a very emotional scene. He was still crying from the scene, and I was impressed by the real tears. I congratulated him on how powerful the scene was. But he shook his head, and said to me, no, he didn’t get it right; he didn’t want to cry at that point in the play, it didn’t serve the playwright. I never forgot that.
