What is the Native American chant/song in Ken Burns documentary “The National Parks: America’s Best Idea”?

In the first episode of the recent Ken Burns documentary “The National Parks: America’s Best Idea” there is a contemporary Native American chant/song in the middle of the episode and it repeats just before the credits. I know I have heard the same song in another recent movie, but can remember or find out which one.
Ok. that link pointed me in the right direction. the song is “coyote dance” by Robbie Robertson. You can listen to it here: http://www.youtube.com/watch?v=Kz_NvNLbeE0 .

It was featured in “Any Given Sunday” and “Bury My Heart at Wounded Knee”.

here is a website for the documentary and this page is about the music. it looks like joseph fire crow is the only native on the list so i would suspect he did the song you are talking about. maybe you can find it there.
