He's not bad. It's really tough being catagorized as "experimental", because people tend to either not listen or hear it once and make a snap judgment. Personally, I don't like or dislike Otto Von Schirach. I can however appreciate that he is making a good effort to try to make something that's off the mainstream.
BTW, you can hear some of his music at
