When I first heard 2:39, I thought of Dark Lich and though they were perhaps cover-referencing that. These dudes were eclectic enough to be a little videogamey sometimes.
Way later I learned of the Balinese Monkey Chant and such, blew my mind. And vocal cords when imitating.
I’m struggling to remember one other game I heard using this; gonna have to dig deep and maybe share later.
