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 dig it. Mostly got into it through punk. It's something I'll listen to live or on drugs more than regular rotation. It's fun as hell to make.
