107 bars at 159 BPM -- fast, and 2:42 of it without a break -- on crash, ride, hi-hat, snare, high tom, mid tom, kick and hi-hat foot.
99 out of 100. Hard, and what makes it hard is the independence between the hands and the feet.
silence through bars 1-10, hi-hat through bars 11-26, ride through bars 27-38, hi-hat through bars 39-54, ride through bars 55-65 and kick and crashes through bars 66-67, and 5 more changes after that.
The beat the song is built on is one bar, played through bars 31-37, 59-65 and 76-82, and 1 more place -- 28.6% of every bar the kit plays. That is the spine of it; everything else is what happens around it.

It cuts the song into 21 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.
159 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.
99 out of 100. Hard, and what makes it hard is the independence between the hands and the feet. The beat itself is 98 out of 100; the rest of the number is everything around it.
107 bars, about 2:42 at the written tempo. The course breaks it into 21 exercises over 9 sittings, about 24 minutes each.
crash, ride, hi-hat, snare, high tom, mid tom, kick and hi-hat foot. That is most of a full kit; the part moves around it rather than sitting in one place.
