119 bars of 4/4 at 120 BPM, about 3:58 of playing, on crash, hi-hat, snare, high tom, floor tom, kick and hi-hat foot.

snare through bar 1, hi-hat through bars 2-17, snare through bars 18-21, hi-hat through bars 22-37, toms through bars 38-49 and hi-hat through bars 50-69, and 5 more changes after that.
