Electronica pioneers from holland in the 60s. Philips had a research facility called natlab (natuurkundig laboratorium). Also: an electric storm with derbyshire is worth checking, as well as raymond scott. For early 20th century mechanical music check out the italian futurist movement.
please checkl out DAF (Deutsch-Amerikanische Freundschaft.)
Amazing, minimal, synth punk. At the itme it was called Neue Deutsche Welle (German new wave.)
+1 D.A.F.!
Anyway, since the early 80s seem to be neglected here:

Please, allow me to semi-goth this up (it fits the site's colours better) with super old Ministry (yes, the metal one, before the metal ;p)
^ That one is from like 81, although that video was shot in 82 i think. Synths used: Opus-3 Moog and Source Moog. Most people weren't even aware the song existed until someone upped that video a couple of years back on le tube.
^ composed some time between 81-84 but released in 85...That track, if I remember correctly, was mostly done with a Fairlight CMI synthesizer. Alot of early Ministry used the CMI. A lot of the Twitch album used it.
^1980 Korg MS-20 for drums... I think it was a CS80 Yamaha used as well... and Black and Decker drill ;P
^ 1983
^84/85 the tune, not the video.
The End. Not classical, but a bit of mixutre of ambience and noise and whatnot... add some Throbbing Gristle, Boyd Rice, SPK etc. etc. and you got the beginnings of industrial music as it was.
