Philip Glass - Pruit Igoe (GTA IV version)

http://www.mp3-2000.com/track/Philip_Glass-The_Grid-mp3-62534.html
The newer version of Pruit Igoe, by Philip Glass, as used in Grand Theft Auto IV and most notably in the first trailer for the game.

I personally think it sounds better and more up-to-date than the original version, which was first used in the film Koyaanisqatsi in 1982.

The video features the entire song and some random pictures of GTA IV. I threw in a few GTA related "gag" pictures I had lying around towards the end of the video as I got kinda bored of choosing pics.
