The beat the song is built on is one bar, played through bars 5-7, 29-31 and 33-35, and 6 more places -- 32.1% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on ride, snare, kick and hi-hat foot, counted in sixteenth notes. On its own it scores 45 out of 100 -- a step up -- and the thing that decides that is how many notes a second it asks for.
The whole song is 69 out of 100, so the beat is not the hard part: what costs you is everything around it, the joins and the fills.
A part this hard is not learned by playing it slowly and hoping. The room opens it on its simplest reduction -- the timekeeper alone, at 138 BPM -- and adds the notes back over 3 rungs, each with a tempo to reach and a gate to pass before the next.
Tempo goes 138, 161 and 184 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
PRACTISE THIS BEAT →A one-bar groove on ride, snare, kick and hi-hat foot, in 4/4 at 184 BPM, counted in sixteenth notes. It is written out above, and it covers 32.1% of the bars the kit plays.
Bars 5-7, 29-31, 33-35 and 57-59, and 5 more places. The time is kept on the silence to start with, and it changes 10 times over the song.
45 out of 100 on its own -- a step up. The song as a whole is 69 out of 100: demanding, mostly on how many notes a second it asks for.
