The Snarky Puppy percussionist explains how drum techniques build upon each other as the easiest levels incorporate the hi-hat, bass and snare drums, and more difficult levels include polyrhythms, the floor tom, ride cymbals, syncopation and much more. br br Director: Sean Dacanaybr Director of Photography: Paul Nealbr Editor: Jordan Caligbr Talent: Larnell Lewisbr br Producer: Maya Dangerfieldbr Line Producer: Joseph Buscemibr Associate Producer: Samantha Vélezbr Production Manager: Eric Martinezbr Production Coordinator: Fernando Davilabr br Sound Engineer: George Searabr Audio: Alain Letourneaubr Cam Op: Jerome W.
