Lets separate topic from "movies", "sleaze", "horror" and whatever into art film.
I know this early 80's film is something probably many have seen, and perhaps doesn't need huge presentation, but if someone has yet to see it:
KOYAANISQATSI Godfrey Reggio experimental documentary about life out of balance. Slowed down film of spectacular natural visions, fast paced film of factories, city life. Such a massive difference in amazing landscapes shot with perfection of film. Towards massive scale urban decay, perhaps captured in nut-shell when showing the demolition of world famous architechtural/social monolith Pruitt–Igoe. Pace of this c. 80 minute film is ever increasing, finally returning to first scene of rocket launch. And the infamous desaster of this technological achievement is pictured in the painfully artistic manner.
Phillip Glass is composer who can sound either utmost genious, or man with mere couple ideas. If you have handful of his albums, you can pretty much rely on knowledge what kind of soundtrack he will provide. I would dare to say that his music works well for soundtrack. The oppressive and hectic style in end, with strange tempo changes are very very "traditional" Glass, yet I fits well into dysfunctional technological hell.
His more relaxing pieces in beginning of film suit my taste the best. Just couple weeks ago, I was driving to trip in forest with my friend, to this natural preserve area, and had
P.Glass CD in car. And came into conclusion, that driving narrow sand road in middle of forest, his music did get into role it deserved! Much better than sitting on chair at your hope. And this movie proves it as well. It is cinematic / visual music.
If you have chances to experience this with proper PA, prober screening, do it. Some dull youtube link with tiny image and laptop speakers of mp3 level sound probably doesn't do the justice.
