The story of the phenomenon that is Kraftwerk, and how they revolutionised our cultural landscape

'We are not artists nor musicians. We are workers.' Ignoring nearly all rock traditions, experimenting in near-total secrecy in their Düsseldorf studio, Kraftwerk fused sound and technology, graphic design and performance, modernist Bauhaus aesthetics and Rhineland industrialisation - even human and machine - to change the course of modern music. This is the story of Kraftwerk as a cultural phenomenon, who turned electronic music into avant-garde concept art and created the soundtrack to our digital age.
