Hey, I'm not shure, if you can open a mediaplayer from Germany. But there was a feature story yesterday in a daily culture program about electric music from Düsseldorf, especially about the beginning of Kraftwerk and DAF. There is a new book about this time, written by a musician from Düsseldorf who makes city walks about this theme. I thought, you might be interested. If the link doesn't work, here is some information about the book (sorry, it's in german)
