151 bars at 164 BPM -- fast, and 3:52 of it without a break -- on crash, ride, hi-hat, snare, mid tom, floor tom and kick.

kick and crashes through bars 1-7, toms through bars 8-13, kick and crashes through bars 14-15, snare through bars 16-19, hi-hat through bars 20-33 and snare through bars 34-37, and 6 more changes after that.
