164 bars at 156 BPM -- fast, and 4:13 of it without a break -- on crash, ride, hi-hat, snare, high tom, mid tom, floor tom and kick.
72 out of 100: demanding, mostly on the independence between the hands and the feet.
hi-hat through bars 1-24, snare through bars 25-32, hi-hat through bars 33-40, ride through bars 41-48, hi-hat through bars 49-63 and snare through bars 64-72, and 9 more changes after that.
