Jazz styles Book

I have the first edition which i just picked up at a used bookstore--its cover is way better--graffiti supposedly sprayed by crazed jazz fans! I picked this book out because (besides the cover) I want to learn some music theory and this book actually has a chapter on Ornette Coleman and a section on Sun Ra. I was getting frustrated that Ornette Coleman is always described as revolutionary-genious-influential in documentaries and then proceeds to get about 2 sec. of airtime and discussion..
