Was this written by the love-child of Philip Larkin and Stanley Crouch?
I agree that there are some valid points there, but the conclusions, such as they are, don't really follow from them. Miles may have been a lot of things, but a fraud? Some of the points read like Larkin, who found Miles's tone lifeless, joyless, and pinched. Some read like that big article by Crouch in the New Republic a dozen or more years ago, where he took Miles to task for betraying his greatness by embracing fusion, retrogressive badass racial stereotyes, and macked-out clothes.
Some of the assertions in the article are downright odd: "So weak was his playing that it had to be overdubbed on his earliest recordings." Huh?
And how about this one: "Furthermore, his music has spoken down the years not to black experience but to white, European lifestyles. There’s a tidy chintziness about Kind Of Blue, for instance, that leads logically to the old theme music to Tomorrow’s World or background music at Seventies Ideal Home Exhibitions."
This piece is all about striking an attitude. Sometimes pieces of this sort can be thought provoking, but I think you captured the overall impression of this one, Chris, with your phrase "largely clueless."
