I mean specifically the more avant-garde stuff based around things like feedback loops, distortion, and white noise, like Merzbow or the Incapacitants. I personally consider it valid as music, but exploring different techniques and sensibilities than "normal" music.
Any noise groups/musicians y'all like?
I don't know where you're at now but I really suggest getting back into making stuff
I really appreciate you saying that. Not really at a good place in my life right now (who is!), but if/when that changes we'll see. Still got all my old equipment!
