The Commandments of Early Rhythm and Blues Drumming from Alfred is a book and CD set that was 8 years in the making. This "prequel" to The Commandments of R&B Drumming delves into the rhythm and blues of the 1940s and '50s, an incredible musical era when shuffles ruled the airwaves and modern groove playing was in its infancy. Written by Zoro and Daniel Glass, drummer for the Royal Crown Revue, this book is loaded with history, photos, graphics, exercises, and transcriptions, and it includes a comprehensive guide to shuffle playing.
