Last week, a friend of ours who lives in the desert area outside Santa Fe was awakened around 3am by coyotes howling in the back of her house. She went outside and saw 4-5 coyotes, who, upon becoming aware of her, began what she referred to as their "kill sound." She went back inside to get her phone to record them, but the light from the phone spooked them and they split.
After hearing her story, I went to http://www.freesound.org and downloaded a bunch of coyote sounds: yips, barks, snarls and howls. I found that if you autotuned the howls, they sound like a Native American flute (perhaps that was the original impetus).
Material is all coyotes, all the time; even the bass drum (continuing the overall Pow-Wow feel) came from a truncated and filtered snarl. C Major pentatonic.
