It's funny, I find myself far more sensitive to the reverse -- musicians who are more process-oriented than results-oriented -- and I also notice that this reverse seems equally distributed between improvisors and the composers: Both camps can often be guilty of proclaiming (overtly or not) "this music is worthy of listening to because it was created by [insert description of some action, plan, structure, premeditated conceit, etc.]" without ever pausing to self-censor because "be that as it may, it still sounds like crap."
I was talking to a friend about this. I was bitching about how I had to hack my way around something in the software. At the end I just said “who cares” since nobody will ever hear my process. They only hear the result (if they listen at all).
