Mike,
I live in Groningen, the Netherlands. We used to have a thriving annual international jazz festival (the "Jazz Marathon") and lots of great jazz concerts way back in the 1970s, but it's kind of dead these days.
You're right, it's best to ignore those musical zealots, though that's a bit harder when you get your head bitten off by one. However, that's not why I didn't renew - like I said it is the lack of modern jazz coverage over the years and the IAJRC's bias towards predominantly white pre-bop jazz, and the price of a subscription ($40, non-U.S. price) to a four times a year magazine that doesn't interest me that much except for the CD review section.
