Yesterday, I picked up UnReel, the drum book by Marc Atkinson. It's a companion to the Randy Waldman CD UnReel. The cool thing about it is that it it has transcriptions of Vinnie Colaiuta's drum solos in it. It also has rhythm scale exercises which look to be very time consuming but essential. I haven't had time to start working on it yet, but along with the Gary Chaffee Patterns book, these two should prove to be what I'm looking for in order to become a better player. Check out the Foreword.
The book is really intense, so if you're not up on polyrythms, look out.
