I played saxophone, so I was into jazz. I learned from each audience and each teacher that I had. I can't really tell you any rules or anything, but the way I develop my beliefs is really just by personally learning from different situations. ↗
Talking about the all night concerts, I did some of the first all night concerts back in the 60's with this little harmonium, and I also had saxophone taped delays. ↗
Throughout the evening I would be recording these long saxophone delays and about four hours into the concert, if I wanted to take a break I would just play back the saxophone. ↗
