I want to second what Michael said. I never worry about the ability of Detroit (broadly conceived, that includes you too, Kzoo :) to bring out excellent music. And the reason is there is 50 years plus of consistent history on that, going back to the great jazz era of the 1940s, followed by Motown, funk, electro, techno, hip hop, house, ghetto/booty/whatever and so on. It's not easy to see from the outside, and it may not be easy to see from inside the region, but the musical ferment there is unique and pervasive. Even though genres and audiences are quite separated now, it's only a matter of time before a period of synthesis starts again, like there was in the early 80s with Mojo and the birth of techno. In fact, the net and MP3 may well be the driver for that.
The point is, there's MP3 and the net everywhere, but Detroit has the attitude and the talent and always will. I'll bet on that, even though I don't gamble :) phred
