What exactly is this? Markus Popp, who is Oval, called it “file management,” and who am I to argue? At the heart of this is the sound of CDs skipping but there is an awful lot of manipulation in play, which could have been done in several different ways (almost thirty years ago now). This is too unpredictable to be ambient (as some call it) and too easy and consistent to be really song-like. It’s digital reflections with no figure, a long rainbow refraction with no lens. It feels like “ribbon storage” to me, but I don’t even know what the ribbon is made of.
