Ok, I admit it, I'm a geek: before going to bed at night, I read a few pages of a textbook or some academic work, generally on jazz. This was the project book from the past couple of months. This wasn't bad, but it was pretty high level. I would take issue with their assessment of Wynton Marsalis as a towering figure at the level of Ellington, Parker, Davis, or Coltrane...after listening to jazz for 40+ years, I'd rate him as a relatively minor figure.
