Ugh. This is awful. I'm not familiar with his work, but, am familiar with the larger picture.
I've recorded a considerable amount of Classical Persian folk music over the years. I've been provided access and privileges to some of their highest level master players. One master in particular told me that their music scholars have shown interest in my recordings of the masters, from here stateside (their new home), because the music has been so repressed/oppressed by fanatical individuals back in their own home country; that the masters here stateside are keeping the old traditional musics alive more so than in their native regions. It strikes me as odd, but, from what I understand, it is a fact of reality there.
Another thing that strikes me as odd, is that music was so much more accepted before the fanatical fundamentalist movements became so prevalent. The Persian players helped to keep Jewish folk music alive at a time when the Jews struggled with just maintaining a life force. So, it is a yin and yang effect with time and history. Now look at these relationships, and imagine such cross-cultural exchanges.
RIP kind gentle sir.
