The beat the song is built on is one bar, played through bars 10-12, 14-16 and 100-106, and 3 more places -- 27.4% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on crash, snare and kick, counted in sixteenth notes. On its own it scores 49 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 57 out of 100, so the beat is most of what the song asks for. Get it clean and the rest follows.
The room opens this beat on its simplest reduction, at 98 BPM, and adds the notes back a rung at a time -- 4 of them. Nothing is a matter of opinion: each rung has a tempo to reach and a gate to pass before the next one.
Tempo goes 98, 115, 133 and 150 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, snare and kick, in 4/4 at 150 BPM, counted in sixteenth notes. It is written out above, and it covers 27.4% of the bars the kit plays.
Bars 10-12, 14-16, 100-106 and 108-114, and 2 more places. The time is kept on the silence to start with, and it changes 22 times over the song.
49 out of 100 on its own -- a step up. The song as a whole is 57 out of 100, a step up from a first song, and the work is in the independence between the hands and the feet.
