"Weathered Stone" by Aphex Twin, I listened to it over and over on the Greyhound bus when I moved to Texas. I looked out the window all the way from Chicago. I remember I wore tan corduroys and a black top. There was a lot of gold september sunshine. I had an empty stomach for days and days and had just turned 19. Such a dream ago. Right now I'm up late listening and baking a cassoulet. I'm in love with the entire Selected Ambient Works Vol. II album.
Also the track "Rhubarb" , "Metal Grating", and "Corrugated Tubing" are all just as intense.
