Eraserhead is literally a sound track album in every way.
Instead of being a collection of songs or score cues, it's a nightmarish mural of decaying soundscapes & awkward dialogues lifted directly from the movie, sounding something like a field recording from a mildly humorous industrial Hell dimension. It roars and rumbles while unsettling soundclips of disturbed sexual frustration and a creepy-ass baby...er...thing cries out from the shadows and every now & then a haunted organ flutters in, courtesy of Fats Waller, and as the rotten cherry on top, the Lady in the Radiator chimes in with her disfigured beauty. A terrifying symphony of noise, David Lynch & Alan R. Splet's sound design isn't for everybody but if this is your kind of thing then bathe in it's dark ambience.
