Once you start thinking about it then you overdevelop it. It should come from the heart, the soul, and the subconscious. It's a jam thing. Music is all about the moment, and if you think about it then you're already in the next moment. Good quote, good quote.
Good quotes are hard to find, by the way.
The performer must listen to the hall, the audience, the instrument, and the other performers. I'm interested in how one listens to an audience. There are three ways of listening, with the ears, with the eyes and the heart. You can make visual contact and make sure that the audience is in rhythm with the music and that gives you a synch, a connection. What you do in music is look for connections, both to the audience and to yourself, deep inside.
