That's kinda their schtick. It's not really my thing, but some metalheads rally get into the tone/noise worship. Personally, any music that is hard to tell apart from a diesel generator is not really my thing, but to each their own.
I guess that is kinda the point I was trying to make...lots of the stuff I like sounds like a pure cacophony.... But there's still order to the chaos even if it's consistently chaos....
