Miles: The Autobiography

It definitely sounds like Miles, doesn't it? The book was published in the late '80s, many years after Miles became a superstar, so his recollections of some events are inaccurate, and he completely misremembers other things, maybe on purpose, to make him look better than someone else (he denies that anyone else had a hand in the composition of Kind of Blue despite strong evidence to the contrary; he frequently contradicts himself when it comes to his racial perceptions). As long as you can put up with that, and you probably will be able to just because the book is so goddamn funny at points, you will enjoy the book. It's a good read as long as you're not taking it at its word.
