101 bars at 155 BPM -- fast, and 2:31 of it without a break -- on crash, ride, hi-hat, snare, high tom, mid tom, floor tom and kick.
78 out of 100: demanding, mostly on how many notes a second it asks for.
snare through bars 1-5, toms through bars 6-8, hi-hat through bars 9-16, snare through bars 17-24, hi-hat through bars 25-30 and snare through bars 31-32, and 5 more changes after that.
The beat the song is built on is one bar, played through bars 9-15, 41-43 and 45-47, and 3 more places -- 28% of every bar the kit plays. That is the spine of it; everything else is what happens around it.

155 BPM, in 4/4, with the time kept in thirty-second notes. At that speed the thirty-second notes are the whole difficulty, so the room will take it down to a quarter of it and climb back.
78 out of 100: demanding, mostly on how many notes a second it asks for. The beat itself is 66 out of 100; the rest of the number is everything around it.
