My go-to artist has been Nasenbluten and BRAINDAAMAGE. I'm looking for something similar with a heavy variety of textures like they use - which- I find a little lacking with other artists of the genre.
To help narrow it down, I don't like songs that just play the same sonic loop for the whole duration of the song with no changes, or very subtle or discrete changes. I basically want a auditory roller coaster- hope that helps.
You can suggest things outside of music, but that's what I'm primarily looking for.
