According to this post by Billy Ward drumming pioneer Jim Chapin has passed away. Best known for his book “Advanced Techniques for the Modern Drummer” (available here on Dom Famularo’s site via Jim’s official site), this book was deemed impossible to play when it was fist published. It eventually went on to become the bible for jazz drummers for generations and is still widely used and recommended to this day. Jim’s book opened many doors for me taking lessons in New Jersey before moving to LA. Thank you for your immeasurable contribution to drumming Jim!
