"Disintegration Loop 1.1 consists of one static shot of lower Manhattan billowing smoke during the last hour of daylight on September 11th, 2001, set to the decaying pastoral tape loop Basinski had recorded in August, 2001. Shot from Basinski's roof in Williamsburg Brooklyn, this is an actual documentary of how he and his neighbors witnessed the end of that fateful day. It is a tragically beautiful cinema verite elegy dedicated to those who perished in the atrocities of September 11th, 2001" - Off the youtube video.
Now I don't know about you, but I find the idea of this pretty brilliant. William Basinski is an experimental ambient artist who releases tons of albums that are all unique in their own way, but it's his collection of albums entitled "The Disintegration Loops" that stand out most for its unique concept and story behind it. The song above has also been the cure to my insomnia for a while now. Slowly, this piece falls apart more and more towards the end and it almost feels hypnotic in a way, just as if a part of you is being destroyed while listening to it. This is not only a relaxing and beautiful work of art, but also very mourning and somber.
Try it out sometime. I recommend just lying down in your bed with this playing. It'll take you places if you let it.
