I recommend Wieland Samolak’s 1993 album, Steady State Music:

When I was a teenager I used to sit on an empty field listening for hours to the sounds of distant cars, railroads, helicopters, and other motorized objects. These sounds, which are very rough and noisy when they are near, attracted me from the distance because they had merged and diffused into a continuum when they reached my ears. By this experience it came to my mind that it is more satisfying for me to listen to continuous changes within one sound than to the combinations of discreet sonic events usually found in music.
