Koyaaniqatsi is the first film of the series, all booking bass voices and spindly tunes.
Then comes Powaqqatsi. So you think after all the lovely tunes and melodies of the first film you expect more of the same.
I'll admit to not having seen the "Qatsi" series of films (Though I've seen Baraka and Samsara, which are similar in theme and cinematography). However the juxtaposition of the clip with the music is brutal.
Saying this, I love when this come on over the car sound system. I go from my normal sedate driver to this moving, steering wheel beating harpy. You just want to turn it up and dance.
And if you get time, hunt out on Youtube the kaleidoscope version of this film. It's freaky.
