Music on the ZX Spectrum. Aphex Twin (Richard D James) in an interview in this documentary, at 2 minutes 24 seconds to 3:26 (link below).
“Early influences were more hardware in nature. An early touchstone was the game loading sound for the early home computer, the Spectrum ZX81.”
“People who had them must have spent hours listening to hat. Its more extreme than any extreme noise music. In time you got to know the sound really well: “Ooh, good bit coming up here.”
It was always the best , sonically, when it tried to load a picture. It would be “lryurrrrrrrrrrrrrrrghh!”
I always wanted to make my music sound like a game! A danceable version of a Spectrum game.”
