Book excerpt: Designed to assist you in developing a real-world vocabulary of drum fills as played by top professional drummers in every style, Filling in the Grooves by Jim Toscano covers all the fills drummers ask about: odd groupings, filling over the barline, hand-foot combinations, double-bass fills, groupings, stylistic fills, and much more. In addition, the book dissects legendary fills played by the giants of the drums, including Billy Cobham, Phil Collins, Stewart Copeland, Steve Gadd, Gavin Harrison, Neil Peart, Simon Phillips, Jeff Porcaro, Tony Williams and more. Included are downloadable digital files containing nine play-along tracks and audio and video demonstrations of nearly every example in the book.
