Given their immense influence on music, you can make an extremely satisfying argument that Kraftwerk has been as important as the Beatles. But unlike the Beatles, they were (and remain) very secretive and mysterious.
The Quietus has helpfully provided this list of 10 things about Kraftwerk of which only the hardcore faithful are aware.
1) On the 1975 Autobahn tour, Kraftwerk were supported by a folk singer from Somerset called AJ Webber. “They weren’t the easiest [people] to talk to, probably due to the language barrier,” she writes, via email. “But they were polite and reasonably welcoming. They drew a certain ‘following’! We warmed to each other as the tour went on.” She also supported Frank Zappa (“I loved Frank!”) supporting bigger bands, as it was just her and her acoustic guitar, so no fancy changeovers were needed in the interval. She also seems to remember that one of them said they had ancestry that went back to Beethoven, but can’t remember the details.
