I was talking with friend who asked me question he had been thinking about lately. Pure noise releases that are... industrial noise. To explain it, one could give example of Con-Dom "Subjection" or some Victor/im, perhaps Mauthausen Orchestra. Sound itself, may be pure noise. No obvious beats, rhythm, synth tone, but there is something that makes it "industrial" or "power electronics" while being musically pure noise.
We did discuss is it merely based on artists other output that puts it in context of industrial culture or is it based on aesthetics. Artwork and such.
Perhaps some of it. Nevertheless, some pure noise one may perceive not to be harsh noise or free improvised experimental noise. He was curious of my favorites of that type and I was indeed caught by surprise but he was genuinely interested in this topic so it feels could be interesting in general!
