What's Neu!?

I've just been listening to the self titled debut by Neu!, a German group founded in 1971 by former Kraftwerk members Michael Rother and the late Klaus Dinger. If you're a fan of Stereolab and Metal Box/Second Edition era Public Image Ltd. you're bound to find the tracks "Hallogallo" and "Negativland" respectively very familiar. And if the title of the latter sounds familiar even if you haven't heard of any of these perhaps you remember the San Francisco based sound collagists of the same name, who named themselves after that track.
