181 bars at 195 BPM -- fast, and 3:43 of it without a break -- on crash, ride, hi-hat, snare, high tom, mid tom, floor tom and kick.

kick and crashes through bars 1-4, hi-hat through bars 5-14, toms through bars 15-16, snare through bars 17-22, toms through bars 23-24 and hi-hat through bars 25-32, and 27 more changes after that.
