I don't think they invented techno. I don't think technos even knew about minimalists. yeah they both got a BEAT that might sound a little similar but they try to achieve very different things. there are some techno artists that consciously use minimalist concepts like the Field, but that's something that came later when techno artists actually had access to stuff like 18 Musicians instead of just club shit
ahhahaha if this would have been done nowdays it would have something stewen wilson would have tried in his solo albums or whatever. IT*S A COOL CONCEPT
but if it was steven wilson it would be more like "fart let's do this just for the fuck of it lol it'll be fun shit dump poop"
