One of the more interesting drum books ever written is Inner Drumming, by George Marsh. Marsh is a big Tai Chi practitioner, and his linear drumming method, using a novel, artistic system of notation, is all about energy flow... the book is sort of like Four-Way Coordination, informed by Eastern philosophy:
I'd like to get those blow-ups of the diagrams. Someone should be selling those.
I spent some time with the book in the 80s, when there was a copy floating around the percussion department at the University of Oregon. I don't think I was ready for it— like Dahlgren & Fine, I think you need to be a fairly developed/mature player to get the most benefit from it. But any ambitious drummer— like someone who would be reading Cruise Ship Drummer!— should own it. For a long time you had to get it from George himself, now it's available from Sher Music. You can read more about the book and about Marsh at his website, and also friend him on Facebook.
UPDATE: Oh, Michael Vatcher! I spaced out for a moment. I once met him at a jam session in Eugene, Oregon, when he was in town on a Creative Music Guild show. It was very random, because he was on a John Zorn record, Spy vs. Spy, which I was listening to a lot right then. He said he and Joey Baron broke a lot of sticks on that session.
