Not only does Zoro teach you the grooves, but he presents great exercises for developing independence, especially to get those happy, stanky feet on the bass and hats. The progression of the lessons was so straightforward that I actually taught myself to read while studying this book.
The best part is that the Commandments of R&B Drumming is FUN. You will not find a more entertaining book anywhere on drumming. Zoro loves this music and it shows in his writing. Since I finished it, I still like to go back and breeze through the exercises just to dig on the grooves.
