164 bars, 32:39, at 20 BPM: slow enough that every note is exposed. Crash, ride, hi-hat, snare, mid tom, floor tom and kick and nothing else.

silence through bars 1-6, kick and crashes through bars 7-8, snare through bars 9-27, silence through bars 28-30, hi-hat through bars 31-34 and snare through bars 35-58, and 9 more changes after that.
The beat the song is built on is one bar, played through bars 116-121, 132-138 and 140-145, and 1 more place -- 16.6% of every bar the kit plays. This one moves around more than most: the beat is where to start, not the whole job.
