[as a saxophonist, a theory on solo performance] What I did was give permission for people to repeat themselves and get into cyclic patterns. The old basic idea of the left brain/right brain split between the rational and the analytic versus the intuitive and the holistic holds true. I think there is something that happens on a good night when I sort of leave the analytic behind and start to deal with the whole story. That might have some kind of correspondence with an altered brain state, or an altered consciousness state.
