I'm going on memory from college days 15 years back on this one but there was a movie we saw on PBS and recorded one evening called Koyanasquatsi that was, at the time, about as unique a show as I'd seen to date.
I'd play it for friends from time to time over the years but the tape quality and the advent of DVD eventually allowed my copy to become buried. I no longer know where it is now but still remember the show pretty vividly.
If I'm not mistaken, it was described as "A non-narritative pictoral essay sweeping across the US in search of natural and man-made vistas" or something close to that. Strong on time lapse photography, it began with beautiful movie shorts of nature, then man's dominance and eventual screwing up of the planet.
Anybody else catch ever this show and develop a fondness for it?
