The beat the song is built on is one bar, played through bars 15-22, 35-42 and 52-59, and 1 more place -- 37.2% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on crash, ride, snare and kick, counted in sixteenth notes. On its own it scores 76 out of 100 -- demanding -- and the thing that decides that is how many notes a second it asks for.
The whole song is 86 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 48 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 48, 58, 67, 77 and 87 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, ride, snare and kick, in 4/4 at 87 BPM, counted in sixteenth notes. It is written out above, and it covers 37.2% of the bars the kit plays.
Bars 15-22, 35-42, 52-59 and 72-79. The time is kept on the silence to start with, and it changes 9 times over the song.
76 out of 100 on its own -- demanding. The song as a whole is 86 out of 100. Hard, and what makes it hard is the independence between the hands and the feet.
