104 bars at 170 BPM -- fast, and 2:26 of it without a break -- on crash, hi-hat, snare, mid tom, floor tom and kick.

kick and crashes through bars 1-7, snare through bars 8-17, silence through bars 18-19, snare through bars 20-30, hi-hat through bars 31-36 and snare through bars 37-54, and 8 more changes after that.
