137 bars at 240 BPM -- fast, and 2:11 of it without a break -- on crash, ride, hi-hat, high tom, mid tom, floor tom and kick.

hi-hat through bar 1, toms through bars 2-13, hi-hat through bars 14-21, toms through bars 22-31, hi-hat through bars 32-56 and ride through bars 57-62, and 12 more changes after that.
The beat the song is built on is one bar, played through bars 33-34, 37-38 and 43, and 7 more places -- 13.2% of every bar the kit plays. This one moves around more than most: the beat is where to start, not the whole job.
