Frequently, I go straight into the studio and see what's around. I might hire a couple of instruments that I've never used - maybe a particular type of electronic organ or an echo unit. Then I just dabble with sounds until something starts to happen that suggests a texture. The texture suggests some kind of mood, and the mood suggests some kind of lyric. That's like working in reverse, often quite the other way around, from sound to song. Although often they stop before they get to the song stage.
Brian EnoStop thinking about art works as objects, and start thinking about them as triggers for experiences... That solves a lot of problems ... Art is something that happens, a process, not a quality, and all sorts of things can make it happen ... [W]hat makes a work of art 'good' for you is not something that is already 'inside' it, but something that happens inside you.
Brian Eno
