The other day Brian Eno was on NPR talking about his process. He likes to have people walk into the studio without any preconceived ideas or written out material. Then he has the musicians improvise within certain constraints. Usually these constraints are more about a mood or a vibe than a particular musical structure. After recording some improvisation, Eno edits and loops the high points into a shape. Miles Davis used this same process for some of his electric albums, like In A Silent Way.
Miles and Eno seem radical, but in a way, they’re just boiling the usual compositional process down to its raw essentials. Really, all composition and songwriting consist of improvising within constraints and then sequencing the best ideas into shape. Usually this improvisation happens in short spurts, inside the composer’s head or alone at an instrument. Using a recording device instead of a sheet of paper can make the process more bodily and immediate, and can help get at playful ideas that might not squeak past the mind’s internal judges and editors during the relatively slow process of writing stuff on paper. Michael Jackson wrote his best stuff by improvising into a tape recorder. There’s something about improvising a performance while being recorded that focuses the mind wonderfully.
Since 2004 I’ve been writing and recording with Barbara Singer in different configurations. The first version was her idea, a band called Blopop. She had some techno versions of pop songs programmed into her MC-909 groovebox, and the idea was that she’d sing and DJ, and I’d improvise guitar on top.
