which book to get?


I am wishing to learn how to listen Jazz and at a deeper level as well, though I dont play instruments, but still keen to discover what i like, what i dont like, actually have limited knowledge of Jazz, so you could say Im a novice.

I'm keen to develop an ability to discern styles and epochs in the jazz history, and so now I am debating on which of the 2 books of which i narrowed down from several choices, I have to choose 1, i can't make up my mind, which shall I get?

The Jazz Theory Book by Mark Levine

Jazz Styles: History & Analysis by Mark C. Gridley

I can only pick one, so which one would you choose?

Many thanks

that's a cool suggestion will look to that, yep and I still would like to get One nice book, almost text book like, but in a freindly written manner that talks about how each eras, players plays the music, im not too concerned with personal life stories - there way too many books floating around which emphasised bios and not on the music although I dont know how to read sheet music, I got a freind who would teach me these sometimes not far way
Listen instead of read; try Louis Armstrong, Duke Ellington, Glen Miller; Thelonius Monk, Sonny Rollins, John Coltrane, Miles. Listen to anything Rudy Van Gelder produced as he was a master at getting the sound right. Don't forget Horace Silver, Lee Morgan and all the great Blue Note recordings of the 50's; I think its the 1500 series that had some of the greatest jazz ever recorded. Vocals, Ella Fitzgerald, Shirley Horne, Frank, Tony Bennett, and on and on...in fact, just listen to all the dead jazz guys except Sonny Rollins because they made the best music ever; very few today even come close.
nothing can educate you better than ticket to a live jazz.
if you don't like it than there's no book or collection that could make you do...
Ken Burns multi-dvd set is a documentary called "Jazz" that initially aired on PBS. It's entertaning, informative and provides historical perspective on the evolution of Jazz starting from the blues.
thanks everyone so far for really being helpful, i also read that"complete idiots guide to Jazz' is better than "jazz for dummies", its hard to decide Ken Burns or Smithsonian Collection of Classic Jazz for that 'first chronologically compiled selection' to start off with, guess either will do, maybe get that Idiots guide as well, and maybe Gridley's Jazz style later on.

Already found i like Duke Ellington's music and really enjoy be-bop (Charlie Shavers and Buck Clayton), getting there slowly.

Cheers
