You see, the thing is, I've been in jams like this. The feeling is totally there among the musicians (and whoever else happens to be sitting around, whether they've paid for it or not, probably, and preferably, not). You are close to silence, Silence with a capital S. You are in tune with silence, the deepest sound of them all. Every sound, therefore, that you make, make with intention, sensitivity, and awareness, has a meaning, an ineffability, a significance. You are listening, Listening with a capital L. You hear what everyone else is doing; you do whatever is necessary, which is usually as little as possible. It has nothing to do with self-expression: it has to do with a group mind.
