71 bars at 155 BPM -- fast, and 1:50 of it without a break -- on crash, ride, hi-hat, snare, high tom, mid tom and kick.
67 out of 100: demanding, mostly on how much of it falls off the beat.
toms through bars 1-15, snare through bars 16-17, silence through bars 18-30, snare through bars 31-32, hi-hat through bars 33-34 and snare through bars 35-44, and 2 more changes after that.
The beat the song is built on is one bar, played through bars 10, 12 and 14, and 3 more places -- 14.8% of every bar the kit plays. This one moves around more than most: the beat is where to start, not the whole job.
