Every drummer should own this book. I think it's very important to know the history of your instrument, whatever your instrument is. This book lays it out from the very beginning, in a very entertaining and visual way, complete with awesome pictures of the drummers who were our musical trailblazers. As a historical book it'd be enough, but, Daniel Glass included transcriptions of beats from classic early R&B songs, which you can hear on the CD included. I had the pleasure of seeing him in clinic when this book came out, and he's one of the most informative and entertaining clinicians I've ever seen. This book captures that. Seriously, whatever style music any drummer plays, they should own this book and absorb everything in it.
