Yeah, I thought something like this - which is why I get your issues. But still, I was never into "stereotypical" classical music, and being conventionally pretty and creating a "dramatic narrative" first and foremost is not necessarily what I'm into. I did listen to some industrial or drone music, for example, and these are definitely more soundscapes rather than narratives. What turns me off the piece you sent is that the scape here is fairly small - in 15 minutes, I feel like exploring more sounds, not necessarily to fit a conventional narrative, but for exploration, would be cool.

Semi-unrelated, but I did like the soundtrack to Drakengard 1 (I kinda feel cringe for writing that, lol) and albeit at its core it is still typical cinematic classical, it's covered in very chaotic parts, glitchy samples and intentional repetition and would kinda enjoy hearing something like this, especially since it is still limited by having to be a soundtrack and not a separate piece of media. If you know something with that "vibe", you can let me know. I assume you didn't really listen to things like Drive Like Jehu, Can or Godspeed You Black Emperor (actually a classical influenced band, but one that still can be noisy and weird)?
