Neu! was recorded over four days in Hamburg in 1972 with Can producer Conrad Plank, and its static, aggressive harmonies and almost (but not quite) robotic sound still has a resonance that echoes even today. As any musician from Add N to X to Sonic Youth, from Stereolab to Cabaret Voltaire could tell you, early '70s Dusseldorf band Neu! were one third of the original triumvirate - alongside Can and Faust - that defined Krautrock.
