Power

Kraftwerk ["Power Station"] is an influential German music group. Their uncompromising electro sound was revolutionary in the early 1970's and influenced new-wave, techno, dance and hip-hop styles. Their fifth [1974] album "Autobahn" was their break-trough in the USA. I remember that I was pretty impressed when I heard them for the first time.
