I think the fighting in the letters has been minimized in recent years. one favorite back and forth in years past was Stefan Jaworzyn's review of the No Music box, and Ben Portis (who put it out)'s rejoinder. there was a good one on the Evan Parker Electroacoustic Ensemble also, as I recall, maybe by Tim Hodgkinson?
