But once you're deep enough in the groove it's unnecessary to go anywhere else! That's kinda the point. Funk is its own reward.
OTOH, there ARE other places to go, and there's other roads to go there on. Options are good,
But thenagin, electric Miles of the 73-74 vintage pretty much went anywhere & everywhere it wanted to, and was deeper in the pocket than last week's lint, so perhaps the options are as limited as the imaginations and souls of the players. The number of people who can TRULY get on the one is a lot smaller than is comfortable to admit - EVERYBODY, it seems, thinks they're funky, and it just ain't so. Everybody's "funky", sure, but not everybody's FUNKY. If they were, Zig Modisette would be just another guy, and that just ain't the case!
I dunno, the only thing about fusion that ever bothered me was when it got to be "product" and/ot masturbatory, which seemed to be most of the time as the 70s wore on.
But as to whether or not it's still alive and/or has relevance, hey zeus Crisco, how you gonna live in a world that's nearly fully electric and fully digital and NOT reflect that in your music w/o coming across as some hopelessly naive idealogue or an old guy from another time. Not that fusion is the ONLY way to reflect that world, but the notion that "jazz" must not include certain tools, and/or MUST conform to certain stylistic traits/fetishes is going to kill the music deaddog dead, if it hasn't already (protestations to the contrary, I say the jury's still out on that one, and the doctors are still working overtime to save the patient).
Trying to pretend that something didn't happen (or shouldn't have happened) is not the same as going back in time and actually preventing it from happening. Blanket attempts to discredit fusion's legitimacy as an input to the jazz melting pot are about as realistic as insisting that color movies were a bad idea, and only half as wise. Or less.
Let the music be what it wants to be, whatever that is. Let the music be what it NEEDS to be, whatever that is. Otherwise, stuff it, mount it, charge admission, hire a tour guide, and sell souviners on the way out.
Sound familiar?
