Every once in a while I'll find a new way of playing something, it will suggest itself. But generally speaking, there's a set sonic potential, and that's in concert with a set instrumental technique.
Z'EVI don't want to see an experiment. Experiment at home - when you show up on stage, I want to see a result. I think a lot of improvisers, you'll see them some nights and they just stink, and they go, "Well, we're just improvising." Like that's a license to have a shitty night!
