The beat the song is built on is one bar, played through bars 42-48, 50-56 and 91-97, and 3 more places -- 24.4% of every bar the kit plays. This one moves around more than most: the beat is where to start, not the whole job.
It is played on crash, hi-hat, snare, kick and hi-hat foot, counted in thirty-second 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 99 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 99, 116 and 132 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 crash, hi-hat, snare, kick and hi-hat foot, in 4/4 at 132 BPM, counted in thirty-second notes. It is written out above, and it covers 24.4% of the bars the kit plays.
Bars 42-48, 50-56, 91-97 and 99-105, and 2 more places. The time is kept on the silence to start with, and it changes 7 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 fine the subdivision is.
