163 bars at 170 BPM -- fast, and 3:49 of it without a break -- on crash, ride, hi-hat, snare, high tom, mid tom, floor tom, kick and hi-hat foot.
72 out of 100: demanding, mostly on how many notes a second it asks for.
snare through bars 1-7, ride through bars 8-56, snare through bars 57-66, ride through bars 67-91, snare through bars 92-99 and ride through bars 100-115, and 3 more changes after that.
The beat the song is built on is one bar, played through bars 10-14, 18-19 and 22-23, and 10 more places -- 25.8% of every bar the kit plays. That is the spine of it; everything else is what happens around it.

72 out of 100: demanding, mostly on how many notes a second it asks for. The beat itself is 58 out of 100; the rest of the number is everything around it.
