Interesting this talk of Charlie's lack of taste. Even in world music he had terrible blind spots - hating practically all Brazilian music, as I'm sure has been discussed here many times. DJ Dolores was about the only Brazilian he seemed to like in recent years as far as I remember. He would also be rude about records like Ibrahim Ferrer's first solo album - ok you may not rate it that highly (I do, actually) but to actively dislike it seemed truly odd to me. But what you did get the feeling was that whatever he said was going to be interesting, without fear or favour... and of course he could be fantastically generous as well.
Likewise looking forward to young Boyd's tome........
