Query: Great book

I am so impressed with the Mike Portnoy Anthology book. It was written with articulate detail to Mike's playing and offers an exceptional look into the creative mind of, in my opinion, the best prog drummer today. I love Mike's drumming and I have learned so much from this book. Mike's transitions from meter to meter are seamless and his creativity in color and texture is second to none. This book does a great job of helping drummers grasp this and will promote and result in more acedemic playing from those who use this book. As a percussion professor, it has also served as a wonderful teaching tool in helping to show the connection between rudiments and drum set playing to students. Thank you for this excellent book!Warren MurrayDirector of PercussionWillamette University
