Eraserhead, Side B

The album has been seen as presaging the dark ambient music genre, and its presentation of background noise and non-musical cues has been described by Pitchfork’s Mark Richardson as “a sound track (two words) in the literal sense”. -wikipedia

The mood and tone of Eraserhead and its soundtrack were influenced by Philadelphia’s post-industrial history. Lynch lived in the city while studying painting at the Pennsylvania Academy of Fine Arts, and was fascinated by its feeling of constant danger; describing it both as a “sick, twisted, violent, fear ridden, decaying place” and “beautiful, if you see it the right way.”[8][9][1] Lynch and Splet used avant-garde approaches to recording on the soundtrack; including crafting almost every sound in the soundtrack from scratch using bizarre methods. The ambiance of the love scene in the movie, for example, was produced by recording air blown through a microphone as it sat inside a bottle floating in a bathtub.[10] Lynch and Splet worked “9 hours a day for 63 days” to produce the soundtrack and all of the sound effects in the film. Splet recalls the sound effects Lynch called on him to produce for Eraserhead as "snapping, humming, buzzing, banging, like lightning, shrieking, squealing” over the five years it took to produce the film and its soundtrack. -wikipedia
