I am always amused at the writings of Ken Burns and Leonard Feather as well. Both are for the novice to learn about jazz, but no one has ever written a complete definitive accounting and if anyone does, no one will publish and if it is published, the lawyers will have a field day with it in court. About twenty years ago I started just such a project from an insider point of view. However family counsel as well as outside counsel, after they had read what was the rough draft, was advised not to proceed further.
So do read the Ken Burns and Leonard Feather documentary on jazz and be happy with that. It is in my opinion the best we have for now and I do respect them for their effort.
