You are quite right to point out that only a few projects/artists have taken influence from the Futurists directly but that was not my point. My point was that noise, atonalism, dissonance, increased volume, abstraction, etc. has been well and truly part and parcel of western music for at least a century, taking the Futurists as a starting point ("since the Futurists", I wrote). I was referring to those elements of western music that would impact on Noise, up to and including Industrial. I am aware of the history of Futurism, by the way.
Personally, I draw a distinction between noise the dictionary definition and Noise the genre. Noise the genre may well be undesirable to mainstream culture but I'm not thinking of mainstream culture when I make it or listen to it. To me, Noise is desirable sound. Those other elements you mentioned I can take or leave as I desire or not.
No, I don't expect their views to be any different from a lot of other people who "make Noise" and that's another reason why I think this documentary is boring. In fact it reminded me of a film made at the start of the 00's of experimental musicians in Queensland, Australia - very similar in many ways. The only difference to me was the regional aspect and that at that time I hadn't seen many films like it, so I understand your enthusiasm to share this film. I'm pretty sure, either on this forum or the Troniks forum, one could track down a list of films about Noise/PE/Industrial if one was keen.
