88 bars at 160 BPM -- fast, and 2:02 of it without a break -- on crash, ride, hi-hat, snare, high tom, mid tom, floor tom and kick.
73 out of 100: demanding, mostly on how many notes a second it asks for.
hi-hat through bars 1-7, snare through bars 8-9, hi-hat through bars 10-17, snare through bars 18-28, kick and crashes through bars 29-37 and hi-hat through bars 38-44, and 5 more changes after that.
The beat the song is built on is one bar, played through bars 1-3, 5-7 and 10-12, and 5 more places -- 29.3% of every bar the kit plays. That is the spine of it; everything else is what happens around it.

160 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.
