Kraftwerk-"Autobahn" (1974)

As a result of frequent trips on the motorway that originated in Dusseldorf, the residence of the Kraftwerk components towards Cologne where the recording studio was located, in 1974 "Autobahn" was published, which made the fourth Kraftwerk album chronologically.
This album definitively marked the change of style of the band, moving away from the krautrock of the first works to be drifting towards entirely electronic sounds.
"Autobahn" was a risky experimental step that musically represented a road trip, spiced up with sounds such as the engine of a vehicle, the noise of the surrounding traffic or the sounds of the radio stations.
"Autobahn" is considered the first recording of electronic music, although there were certainly others before this one, none had the repercussion that this work had for the later development of electronic pop music.
