Kraftwerk: Pop Art, BBC Four
Kraftwerk go under the microscope for this portrait of the artists
Some documentaries can feel like trying to view a desert landscape through a telescope. The need for tight focus on too large a subject can leave you constantly aware that there’s important stuff going on out of eyeshot. The stuff you can’t see becomes a constant irritant, like a pending tax return, or David Starkey. Kraftwerk: Pop Art, in significantly narrowing its focus, was more like studying a Petri dish under a microscope – and just as fascinating.
