Brian Eno:

I remember an early review of one of my ambient records saying something like “No song, no beat, no melody, no movement”—and they weren’t being complimentary. But I think they were accurate, because this is a music of texture and sonic sensuality more than it is any of those things they were alluding to. I’m sure when the first abstract paintings appeared, people said, “No figure, no structure,” etc.… The point about melody and beat and lyric is that they exist to engage you in a very particular way.
