yep exactly what I am pointing to. I meant performance based in that its complexity comes from how it interacts with culture language, other music, ideas, etc: cultural production. True also of classical composition, but as you say, it's already been done, and so the pattern can be reproduced. I was also adding the idea that the mathematical and notational rule-logic of a lot of classical music lends itself to machine based reproduction in ways that modern pop pastiche does not, and that's counter intuitive as some comments noted, because the actual product itself is entirely machine mediated.
