I was listening to WCN 3xCD set, and CAPERS interview clip has short piece where Oskar asks is there any rules to Capers stuff, and artists says (among other things) "it has to be slow".
Pace, tempo, of noise is curious, since if there is no obvious rhythm, sometimes you can't really decide is the stuff you are listening really slow or utterly fast stuff. A lot of HNW is like that. Back in the day when I first heard Hijokaidan and Incapacitants, those I also felt like were slow. If Pain Jerk, Merzbow, Monde Bruits, Killer Bug etc most often busy in modulations, changing the sound, cutting things, etc. While Hijokaidan and Incapacitants are actually really damn fast, I always got feeling of "stillness", since the overall atmosphere might not move much.
The topic subject here, it is still different. Capers certainly moves slow. Also I often associate Hum of The Druid among slow noise. Haters can be often slowly grinding something. Old Death Squad, many Dead Body Love... massive elements of colossal noise rumble, and I often got impression of slowness.
When thinking about NOISE, that isn't like death industrial or dark ambient, but real deal noise, feelings about the tempo of material?
