I have filing cabinets full of drum books. Between years of buying them,and now reviewing them for Percussive Notes, I have quite a collection. After speaking to my insurance agent, I realized that I had to inventory all of them. I started a while ago, but have to get back to it.
An interesting one is Jim Chapin’s Advanced Technques for the Modern Drummer book 2 “The Open End”. It is ring bound with cutouts and overlays.
