The beat the song is built on is one bar, played through bars 6, 8 and 10, and 13 more places -- 42.3% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on ride, snare and kick, counted in thirty-second notes. On its own it scores 57 out of 100 -- a step up -- and the thing that decides that is how fine the subdivision is.
The whole song is 71 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 68 BPM -- and adds the notes back over 4 rungs, each with a tempo to reach and a gate to pass before the next.
Tempo goes 68, 81, 93 and 105 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 and kick, in 4/4 at 105 BPM, counted in thirty-second notes. It is written out above, and it covers 42.3% of the bars the kit plays.
Bars 6, 8, 10 and 20, and 12 more places. The time is kept on the silence to start with, and it changes 3 times over the song.
57 out of 100 on its own -- a step up. The song as a whole is 71 out of 100: demanding, mostly on the independence between the hands and the feet.
