Frankly, I see a lot of arrested developement, people so in love with the notions of "art" and "artist" that simple day-to-day responsibility, like the act of paying a bill on time would shatter their creative world (I exaggerate, of course, but...). Hell, just grow the fuck up and accept the responsibility for all of your life, ya' know? It's been done, right? Miles was a freak, but he handled his business, as did Trane, as did any other number of people.
For every truly tortured genius like Bird, Bud, or Monk (although is "tortured" the right word for Monk?), there's at least as many, probably more, cats who just don't want to grow up & they construct all sorts of elaborate premises as to why they can't/shouldn't. I'm not talking about the cats with real bio-chemical problems either, just the ones who are always looking for a scam or a con or some other way to get you to handle their business for them. If the Gil Evans bio was to be believed, he was one of those type, and god knows that I love Gil Evans, but the lamenting of his rather limited output over the years could probably be just as directed at him as at any "industry indifference". That's what I'm talking about.
