While many books teach the "open roll," Master Studies teaches the controlled roll. Morello’s method for developing the "multiple bounce" stroke (the buzz roll) and the "stroke-out" double stroke is arguably the best ever written.
Before writing his own book, Morello was a star student of George Lawrence Stone, the author of the iconic Stick Control . Stone was so impressed by Morello’s creative additions to his exercises that he dedicated his next book, Accents & Rebounds , to him. joe morello master studies pdf link
