"These tracks, recorded from 1976-83, are an appealing mix of artsy electronic ambiance and progressive Krautrock. Eno's mechanical 'Broken Head' stands out as the only vocal track - a dark, almost oppressive industrial tune. 'Speed Display' is a fantastic showcase for percussionist Mani Neumeier's speed and endurance. He generates an incredible rhythmic groove, supplemented by sparkling synthesizer flourishes. Roedelius shines with two contributions to the set. His atmospheric 'Mr. Livingstone' is an Asian-influenced synth piece with percussion. Along similar lines, the warm colors of 'Langer Atem' may have been inspired by Eno's more melodic ambient work, perhaps Music For Films. Moebius and Plank's 'Conditionierer' scores as upbeat, quirky synth rock."
