that's what came to mind for me too. optimism in the air. the future just around the corner and everything's going to be alright. you hear it in the music - a sense of journey, moving forward, exploration. hints of uncertainty, but the collective conscious hasn't been contaminated yet. hope reigns. good will overcome. earnestness was legal tender.
edit: at least that's how it feels to me, but i grew up in the 90s so it's probably rose tinted.
I mean this is why I think a lot of 80s electronic music sounds more futuristic than 90s electronic music, 92-93 darkside jungle, hard acid/gabber/dirty electro excluded.
You listen to what Severed Heads or SPK were doing in the 80s and its miles above like Future Sound of London or Biosphere, even above most garage in terms of its angular alienating textures. Not that I don't have a soft spot for the biosphere substrata album, just noting that hindsight problematises the futurism we like to gush about on here.
For me darkness isn't a satanic pose or whatever, it's not even necessarily an aesthetic pose, it's just the every day reality. For me the problem with escapist music isn't that it is bourgeois or whatever (I'm not an SWP hack) but paradoxically that the shiney surfaces sound cheap, they sound like something recyclable. Paradoxically a lo fi acid jam feels more like a lushly orchestrated 70s disco production to me, because we've pushed expansive clean production to its material limit. In that sense I agree with barty that future can only now be dystopia because we saught utopia prematurely. We killed that future with our own hands.
