What a piece! One groove, tons of variations, tasteful choice for leaks... You can study and practice part of it as the whole piece, it will make you improve your time, your coordination and how you actually sound on the kit anyway. Chris Daddy Dave is really the "Most Dangerous Drummer Alive!"
Some notes are missing, it's difficult to catch every note but still, you have almost everything. Feel free to adapt the score on your own drum kit if something looks too difficult, as we don't have Chris Dave Drumset. Enjoy!
