The beat the song is built on is one bar, played through bars 51-64, 67-71 and 76-77, and 3 more places -- 15.7% 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 hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 88 out of 100 -- hard -- and the thing that decides that is how many notes a second it asks for.
The whole song is 93 out of 100, so the beat is most of what the song asks for. Get it clean and the rest follows.
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 126 BPM -- and adds the notes back over 5 rungs, each with a tempo to reach and a gate to pass before the next.
Tempo goes 126, 152, 177, 203 and 229 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 hi-hat, snare and kick, in 4/4 at 229 BPM, counted in sixteenth notes. It is written out above, and it covers 15.7% of the bars the kit plays.
Bars 51-64, 67-71, 76-77 and 181-193, and 2 more places. The time is kept on the hi-hat to start with, and it changes 24 times over the song.
88 out of 100 on its own -- hard. The song as a whole is 93 out of 100. Hard, and what makes it hard is how many notes a second it asks for.
