thank you! this is actually almost exactly something i had meant to say earlier. i was going to make it more specific to improv/EAI, though: i think it's hard to evaluate what's "good" in this genre (as opposed to say, really fast/precise metal solos, or "well-balanced" jazz solos) because ideally (for me, anyways), the best improvisation creates its own language as it goes. and i think a ton of things can go into that language: some people elevate technique, others quite purposefully pervert or ignore it. the placement of sounds is contextual, and formed by expectations created earlier. those expectations can be realized or subverted, etc. so i think it's hard to talk about what's "good" when we are so frequently looking for actual paradigm shifts. i think brian olewnick's blog does a good job capturing this, as i think his frequent reviews sometimes mention finding something pleasant or well-done without having an extra layer of intrigue, versus reviews where he talks about something getting deeper.joe grimm wrote: 1. a piece is good when it causes me to reevaluate the conventions of its medium... in some small way, it changes the rules of the context in which it operates.
