Steve or Michael- I'm certainly not a truly experienced musician, but I'm curious: how do both of you approach improvised music in general? I've listened to things like Steve's "Drifting" mp3 and most recently the McGill/Manring/Stevens cd and I was wondering how this stuff actually starts. I mean, do you have things in mind when you start one of these tracks? A chord structure? Or are some parts actually written out?
