Seeing the arc of Cabaret Voltaire over the course of these years and styles is one of those slightly disorienting experiences, in that even with the notable lineup change occasioned by Chris Watson’s departure in 1981 it’s all clearly the same band using carefully different approaches as they see fit. And who can blame them: whether it’s the defiantly lo-fi “Do the Mussolini,” the blasting “Nag Nag Nag” or the later, almost surprising commercial successes of “Just Fascination” or “Sensoria,” their command of electronic aggression was unparalleled.
