Art and Kraft

Wonders will never cease. Not only are Kraftwerk busy dazzling audiences up and down the country  with a (by all accounts) astonishing live show that most probably never thought they'd get to witness, the German pioneers have also granted an interview. In conversation with the Guardian's Tim Jonze, Ralf Hutter isn't hugely forthcoming - his responses are guarded and often somewhat elliptical - but he does talk about technology, politics, his band's origins and their enormous musical legacy.
