I really like this guide a lot. Todd makes it easy for you to start learning the various techniques that will help you develop your own style. He's pretty good too. I don't like all the insanely fast rhythms I've heard from other artists. Todd breaks it down slow and works his way into nicer complex beats that you will feel as well as follow along with.
