[In the words of…] Brian Eno

«There´s an experiment I did. Since I did it, I sarted to think it was quite good exercice that I would recommend to other people. I had taken a DAT recorder to Hyde Park and near Bayswater I recorded a period of whatever sound was there: cars going by, dogs, people. I thought nothing much of it and I was sitting at home listening to it on my player. I suddenly had this idea. What about if I take a section of this -a 3½ minute section, the length of a single- and I tried to learn it? So that´s what I did. I put it in SoundTools and I made fade-up, let it run for 3½ minutes and fade it out. I started listening to this thing, over and over. Whenever I was sitting there working, I would have this thing on. I printed it on a DAT twenty times or something, so it just kept running over and over. I tried learn it, exactly as one would a piece of music: oh yeah, that car, accelerates the engine, the revs in the engine go up and then that dog barks, and then you hear that pigeon off to the side there. This was an extremely interesting exercice to do, first of all because I found that you can learn it. Something that is as completely arbitrary and disconnected as that, with sufficient listenings, becomes highly connected. You can really imagine that this thing was constructed somehow: «Right, the he puts this bit there and that pattern´s just at the exact same moment as this happening. Brillant! Since I´ve done that, I can listen to lots of things in quite a different way. It´s like putting oneself in the role of an art perceiver, just deciding, now I´m playing that role»
