81 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.
72 out of 100: demanding, mostly on how much of it falls off the beat.
silence through bars 1-7, hi-hat through bars 8-32, kick and crashes through bars 33-41, hi-hat through bars 42-58, silence through bars 59-65 and hi-hat through bars 66-81.
The beat the song is built on is one bar, played through bars 9-16, 25-27 and 29-32, and 1 more place -- 33.3% of every bar the kit plays. That is the spine of it; everything else is what happens around it.

It cuts the song into 15 exercises -- the grooves, the fills, and the joins between sections, which is where players actually come off -- and puts them in the order a teacher would. Each one opens on a reduction you can already play and adds the notes back a rung at a time, with a tempo to reach and a gate to pass before the next.
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.
72 out of 100: demanding, mostly on how much of it falls off the beat. The beat itself is 67 out of 100; the rest of the number is everything around it.
81 bars, about 2:02 at the written tempo. The course breaks it into 15 exercises over 5 sittings, about 24 minutes each.
crash, ride, hi-hat, snare, high tom, mid tom, floor tom and kick. That is most of a full kit; the part moves around it rather than sitting in one place.
