111 bars of 8/4 -- not four -- at 247 BPM, 3:00 of playing on crash, ride, hi-hat, snare, high tom, mid tom, floor tom, kick and hi-hat foot.
85 out of 100. Hard, and what makes it hard is how many notes a second it asks for.
toms through bars 1-2, ride through bars 3-10, hi-hat through bars 11-18, ride through bars 19-21, toms through bars 22-23 and hi-hat through bars 24-27, and 11 more changes after that.
The beat the song is built on is one bar, played through bars 3-5, 7-9 and 19-21 -- 13% of every bar the kit plays. This one moves around more than most: the beat is where to start, not the whole job.

247 BPM, in 8/4, with the time kept in thirty-second notes. At that speed the thirty-second notes are the whole difficulty, so the room will take it down to a quarter of it and climb back.
85 out of 100. Hard, and what makes it hard is how many notes a second it asks for. The beat itself is 66 out of 100; the rest of the number is everything around it.
