Yay another Kraffie fan! *dances with Flammenstrahl*
they have managed to capture something from that timeespecially with their older stuff... Listening to some songs I can almost smell and feel things from my childhood, the memories are really sharp.

hock: Listening to Autobahn I can even taste the 70's even though I wasn't even born then!

Of course, things like that go away after you listen the songs enough. Happened with another 80's band too, I got the same kinda freaky sharp memories, but by listening more, I "transferred" the music into present day and the memories didn't get activated anymore. Shame, really. :|
What's great about Kraftwerk is that their music is basically so positive, happy and sometimes even romantic. They have all these electronic sounds, but they don't try to make it sound even remotly threatening. Describing it as "kind and friendly" and "cat-like curiousity to experimenting with sounds" wouldn't be too far off, methinks.
I think you should try to find something by the band Skanfrom.I dowloaded the three songs, and now after listening them once, they seem kinda boring... but maybe they improve after a while!
