Reddit mentions of Jazz: From its Origins to the Present

Jazz: From its Origins to the Present is a super great book. Very in depth look at jazz from its inception to now without a moment of dry-ness. I also would recommend Miles: The Autobiography as more of an entertaining/supplemental read. It's a super interesting book, that follows Miles through his upbringing in Bebop with Bird and Dizzy throughout his entire genre-spanning career. There are some really great anecdotes about a lot of jazz musicians in there.

Edit: I forgot another great thing about the first book is it has a lot of examples and transcriptions so you can see the distinctive styles of a lot of great players as well as the vernacular used in each jazz era.
