It's on my to-read list! I'm currently reading "History of Jazz" by Ted Gioia (simply wonderful!), which I use to update all my entries. If I could recommend another excellent Italian book (written by Giorgio Lombardi, the guy who introduced concerts at the jazz club in Genoa, my hometown), it's "New Orleans Chicago New York," a magnificent history of the origins of jazz. Thanks for the recommendation, I really appreciated it. ciao!
