I was watching the Portland topic.. and recent days reading the Death Squad USA 1997 tour book. Makes one think about time. There are several occasions where in the book is mentioned that when figuring out what happened to couple cool guys who organized show, they were already dead.
Some, if not dead, could say ageing.
In other hand, when reading WE KNOW HOW TO HATE book, dealing with Frans De Waard tape label from 1985-1986, most of people behind those projects were still possible to reach. That is curious. Of course, if you were 15-20 years old, 40 years later you might still be in peak of creation (hah..), but it makes one consider if different approaches, different styles of noise has kind of... longevity? Lasting power?
Also new WCN podcast with Osaka in Winter Adam discussing the changes in Chicago live noise culture. Specific years of mixed bills, influx of new crowd, then separation, cliques and things just sort of disappearing.
In sense, that people into local live noise scene - I would estimate a lot of people come and go. In terms of physical international art, it is often amusing to see how many of the same guys are there since the 80's! Like DS book may display, local scenes disappear when couple key figures no longer than and the crucial venues no longer there, but some timeless elements of noise remain.
Still, I would guess than we are indeed approaching in decade or two, the moment when originators and active people no longer there. Change could be drastic and fast.
Probably a lot of folks wouldn't even notice and also makes one think what are the things with some sort of foundation of later age noise and if they have same lasting impact? Or does it mean anymore if culture exists more in pop up temporary things.
