When I first began listening to jazz years ago I was overwhelmed by the amount of stuff out there. I didn't have a lot of money so I didn't want to buy albums that I wouldn't like. I wanted to get the best. This book was a god-send. Of the 100 or so jazz albums I own, I have only returned two that were recommended by this book. Most of the jazz I own was purchased after studying this book. The info is great, the reviews are usually on target and easy to read (what is so hard about the stars?). If you are just getting into jazz, or need info on an artist that you don't know anything about, get this book. ESSENTIAL.
