I can appreciate bringing music to people through "found" objects...street kids musicians have been doing it for years, but theirs is full of variety, sometimes tonal, sometimes full, sometimes minimal; always listenable. As in the provided link, I still find his stuff boring and pretentious and un-listenable. I know I am partially prejudice because of the following:
The professors at Denver University and Southern Illinois were so enamoured of him they told students who wrote anything tonal that their stuff was no good, would never be heard, etc., etc. and would throw it out. It took years for some of the students, including my brother, to get their professors' voices out of their heads, believe they had a valid voice and could write tonal, beautiful music, even blend some dissonance into it without losing the integrity of what they heard/felt within as they composed.
I don't wish him any ill will and it is sad that he has passed on, but I can't say I'll miss his music.
