If you left it all night and came back the next day, it sounds strangely familiar and warm, in a way that a computer couldn’t have done, or a plug in couldn’t have done. It started to invoke the sense of memory or place. It had a real kind of homey, organic human sound. We created probably 30 of those things and would let them go for various amount of time, depending on how well they deteriorated. That provided the foundation for all of the heartfelt motifs in the picture.
It was a recording technique we discovered that we’d been thinking about, but we hadn’t really had a reason to deploy it. That become something that we then used for everything else in the whole score. We’re not imagining anyone would hear that and say, “I wonder if they used several tape decks talking to each other?” It provides a road map that, if we pay attention initially, we start to wait for those things to kind of reveal themselves. That gives us the kind of fenced-in world for that film.
