At no point is he willing to step back and let the material speak for itself. Of course to do that would be to risk losing control. It is an art which is constantly dedicated to discovering the new, to reinventing melody. I'm still watching Ken Burns's jazz series and still complaining about it. Part of the ponderousness of the series lies in that fact.
Jazz is an art of questioning, a reinvention of melody.
Burns is telling you one thing after another. I belong to a lot of groups. But, all in all, I'd rather listen to Louis Armstrong.
