For me it's always contingent on getting a sound-the sound always suggests what kind of melody it should be. So it's always sound first and then the line afterwards.

This enabled sound recorded on the first deck to be played back by the second deck at a time delay that varied with the distance between the two decks and the speed of the tape (typically a few seconds). These tapes had previously been used as backgrounds in some of his collaborations with Fripp most notably on Evening Star. Eno has also worked on records by James Laurie Anderson Coldplay Depeche Mode Paul Simon Grace Jones and Slowdive among others.

It has also been extremely influential pioneering ambient and generative music innovating production techniques and emphasising "theory over practice". Brian Peter George St. Eno's solo music has explored more experimental musical styles and ambient music.
