Currently, I've been playing for 6 years and I can't seem to get enough of the book Stick Control by George Lawrence Stone, how many drummers out there use this book? Because it's to me, a lifetime full of rudiments.
George stone's Stick Control is the best book I've ever used. If you actually read what it has to say and practice how you are supposed to, there is nothing that you shouldn't be able to do with your hands.
The book is quite repetative, but it has helped me so much over the years and like I said after 6 years of playing I'm still not done learning the things In it and switching everything around, sometimes I do the book with my hands and feet, or just feet, great way to build up endurance and chops.
