The album actually sounds like you think it would, dominated by metallic plinky pongy tones. But even tho these songs are indeed produced only by Bertolozzi's molesting of a great Parisian structure, they are not just random banging. They are structured, highly rhythmic, even weirdly melodic, with each track having it's own peculiar flavor. In other words: musical. Here's one particularly toe-tappin' sample:
