106 bars of 3/4 -- not four -- at 230 BPM, 1:31 of playing on crash, ride, hi-hat, snare, high tom, mid tom, floor tom and kick.

snare through bars 1-3, ride through bars 4-7, snare through bars 8-9, hi-hat through bars 10-13, snare through bars 14-15 and silence through bars 16-17, and 15 more changes after that.
