Krautrock

I love electronic music and synthesizers. 
The music out of Germany in the 1960's and 70's was wonderful.

Nice history at Reverb:

The Synths and Electronic Gear of Krautrock
Something incredible happened in Germany in the late 1960s. A generation of young people, equally determined to not follow in their parents’ fascist footsteps and not copy American and British styles of music, set about creating their own. This was not an organized movement like punk or rave, but kismet. Musicians all over the country simultaneously decided to forge something new from the cultural ashes of their country.

It wasn’t a unified movement: there were as many ways of going about this as there were bands doing it. Novel ways of playing, such as improvisation, were common, as were unusual tunings and rhythms. This embrace of the new went beyond how they played their instruments and encompassed the actual instruments themselves. Certainly there were bands playing standard instruments like guitar, bass and drums, but others gravitated towards the new electronics that were emerging, including nascent synthesizers, drum machines, and effects. There were no rules—if it could make a noise, it could get thrown into the mix.

It was also often a sound honed in the studio, away from prying ears. David Stubbs, the author of the excellent book on Krautrock music, Future Days, explained it to me like this when I reached out: “Attaining an independent studio space was of the utmost importance to early Krautrock bands including Faust, Can, Kraftwerk—a space in which they could operate independently of the mainstream, commercial rock/pop conveyor belt, construct their own sound, West German in origin, from scratch. Electronics naturally played a starring role in this initiative. (Producer Connie) Plank was of great assistance but also the likes of Kurt Graupner, who devised ‘black boxes’ for Faust at their Wümme studio in 1971-2, enabling them to ‘jam’ and splice together their sounds in unorthodox ways.”

Much more at the site - nice essays about the various bands and the equipment they used.
