Quad Logic by Bill Bachman

This book is designed as an instructional tool for quad players and as a guide for those wishing to better understand the instrument. The issues covered are those which are unique to quad players. The book is best used in conjunction with other rudimental books (such as Rudimental Logic). Develop your rudimental vocabulary there, and learn to move it around the drums here. For example, this book does not teach basics of playing flam drags, but it does show you how to play them crossed over on a set of quads.
