not sure exactly what can be done. part of the problem here is that techno tends to be played at smaller clubs (unless a heavy hitter like mills or hawtin is in town) which usually results in smaller crowds and not too many new people getting exposed. personally, i think the biggest problem techno faces here (and from what i imagine it's a similar problem everywhere) is that new people, and especially kids, aren't getting into it/exposed to it. so it's kinda the same people who have been listening to it all these years. and these same people are getting older, getting jobs, getting families, etc so it's harder and harder to go out every weekend and support "the scene". so long story short you need to get people exposed to it that wouldn't usually have an opportunity to hear it--to recruit new blood, you know?
and on the bright side, i def think techno still has great appeal. when Sims was in town last month some girls i work with came out to check it out--they'd never really been to a techno night before. two of them really liked it and where asking when the next event would be. hell, one of them is even planning on doing the stacey pullen night for her bday. sht, like that is encouraging, shows that this music is still valid and the events appealing--again, just a matter of getting these new people to hear it and get interested.
you did a desert show out in AZ? man, that sounds fun. my parents actually just moved to Tucson, you AZ guys gotta keep me posted on what's going on out there.
