Early techno music – not too surprising that it came out of West Germany.
“Autobahn” off the album Autobahn by Karftwerk. The album version was one side of the vinyl – so 22 minutes and then some. It was edited down to 3 minutes 27 seconds, and a bit to be released in the US as a single. The album (Kraftwerk’s 3rd) was released in November of 1974 and the single was released on the 7th of May in 1975.
Kraftwerk is one of those bands that you should know about, and probably don’t. They paved the way for a lot of things that came later.
