For the last several years Ive been involved in non-profit organizations which produce jazz concerts in Our Fair City. Theres a clear pattern: Dave Brubeck or Wynton Marsalis will sell out the biggest hall in town. Theres probably a pool of not more than several hundred people who might come to see a mainstream jazz show say, Bobby Watson and only about half of them want to come out on any given night, of course. As for Jazz-of-This-Moment, its even sadder: A concert by, say, Matthias Lupri or Bill McHenry essentially never draws a hundred people. Obviously, the key is to get those Brubeck/Marsalis/Krall fans out for shows by jazz demi-gods and mere mortals. Here are some of the things that were tried so far: * Fine publicity. The last big fest had killer newspaper coverage, strong TV spots, radio giveaways, thousands of targeted fliers and hundreds of posters. The Moment-fest also has strong newspaper coverage, radio giveaways and lots of fliers and posters. * Timing. The big fest moved from Labor Day weekend to late September with only modest effect. * Pricing. Wynton was $40; a big-name modern-jazz double-bill is usually $20; Now-Jazz tix are usually only $15. My question to you, o thoughtful folk, is this: Have you actively confronted this phenomenon in your town? What has worked?
