Cologne and Düsseldorf sit roughly forty minutes apart on the Rhine, and in the early 1970s that corridor produced a body of music unlike anything being made anywhere else on earth. The two cities were not collaborating in any organized sense. They were running parallel experiments, drawing on different institutional resources, arriving at different sounds, and yet producing work that cohered into something critics would eventually call krautrock. The proximity mattered less as logistics than as atmosphere: two cities close enough to share a cultural moment, far enough apart to develop distinct answers to the same question.
The question, put plainly, was what German music could sound like after the war. The generation that formed these bands in the late 1960s had grown up in a country that had forfeited its cultural inheritance. Traditional German forms carried the weight of what had happened. Anglo-American rock was available but felt like someone else's language. As Dieter Moebius of Cluster and Harmonia later put it, the young musicians of that generation were "tired of listening to bad German music and imitations of American music." Something had to be built from closer to zero.
Cologne had an institutional head start. The WDR Studio for Electronic Music, founded on 18 October 1951 by Herbert Eimert, Werner Meyer-Eppler, and Robert Beyer, was the first facility of its kind in the world. It was not a rock studio. It was a laboratory for electronically synthesized composition, and it attracted the most rigorous avant-garde minds in postwar Europe. Karlheinz Stockhausen took over its direction in 1963 and spent the following decade making it the most consequential address in experimental music. When Irmin Schmidt and Holger Czukay formed Can in Cologne in 1968, they brought Stockhausen's methods into a rock context: Schmidt had studied under him directly, and the band's approach to improvisation, repetition, and the studio as a compositional instrument owed a clear debt to that lineage. Can's 1969 debut, "Monster Movie," with vocalist Malcolm Mooney and drummer Jaki Liebezeit, was already something that had no obvious precedent in rock.
Düsseldorf's inheritance was different. The city's Kunstakademie, where the Fluxus artist Joseph Beuys ran a department and shaped a generation of students, made the visual arts and music unusually porous. Beuys was instrumental in establishing the Creamcheese club, which hosted art happenings and, from late 1970, the earliest Kraftwerk performances. Ralf Hütter and Florian Schneider had founded Kraftwerk in March 1970, after leaving their previous group Organisation, and the Düsseldorf art scene gave them a context in which music and conceptual practice were not separate disciplines. Schneider's father, the architect Paul Schneider-Esleben, had designed the Mannesmann skyscraper on the Düsseldorf waterfront and Cologne-Bonn Airport, and the family's proximity to the postwar German art world was not incidental to the band's sensibility.
The figure who connected both cities was Conny Plank. A trained sound engineer who had worked at Rhenus Studios in Cologne from 1967, Plank recorded Kraftwerk's debut album at Rhenus in the summer of 1970. When Klaus Dinger and Michael Rother left an early Kraftwerk lineup in 1971 to form Neu!, they took Plank with them. The three of them recorded Neu!'s self-titled debut across four nights in December 1971 at Star Studios in Hamburg, and the album appeared on Brain Records in 1972. Plank's credit on that record is producer and engineer, and his role was more than technical: Dinger later described him as a "mediator" between two musicians whose instincts were often in direct opposition.
The opening track of that debut, "Hallogallo," runs for just over ten minutes and establishes its terms in the first few bars. Dinger's drumming holds a steady, unwavering 4/4 pulse, kick drum and hi-hat locked into a groove that neither accelerates nor decelerates, while Rother's guitar moves above it in long, gliding phrases. The beat would come to be called "motorik" by critics and listeners, though Dinger himself preferred the German phrase "lange gerade," meaning "long straight," or "endlose gerade," meaning "endless straight." The distinction is not pedantic. "Motorik" implies a machine quality; "lange gerade" implies a road. Dinger was thinking about forward motion, not automation.
The second track on the album, "Sonderangebot," and the third, "Weißensee," extend the logic in different directions, the former more abrasive, the latter more spacious. The album's second side is organized as a suite called "Jahresüberblick," which contains "Im Glück," the nine-minute "Negativland," and the closing "Lieber Honig," the only vocal track, sung by Dinger. Six tracks in total, all written by Dinger and Rother, all produced by Plank. Upon release, the album sold around 35,000 copies in West Germany and was largely ignored internationally. That number looks different in retrospect.
What Neu! and Can shared, despite their different sounds, was a commitment to duration and repetition as compositional tools rather than as failures of editing. Can's "Tago Mago," released in 1971, spread across two LPs and included tracks that ran past seventeen minutes. The motorik beat and Can's hypnotic basslines both derived their power from the same principle: that a groove sustained long enough stops being a groove and becomes an environment. The listener stops waiting for the next section and starts inhabiting the one they are in. This was not an accident of improvisation. It was a deliberate structural choice, and it required a different relationship to the studio than rock music had previously demanded.
Kraftwerk's trajectory through this period was its own. The band's first three albums, "Kraftwerk" (1970), "Kraftwerk 2" (1972), and "Ralf und Florian" (1973), were made with Conny Plank and documented a group still assembling its vocabulary. The Kling Klang Studio, which Hütter and Schneider established on Mintropstrasse in Düsseldorf, became the laboratory where that vocabulary was finally fixed. By 1974, when "Autobahn" appeared, Kraftwerk had moved decisively away from the krautrock context and toward something that would eventually be called electronic pop. The forty-minute corridor had produced its most commercially legible act, and in doing so had also produced the clearest evidence of what the scene had been building toward all along: a music that was entirely German in its references and entirely new in its form.
The term "krautrock" itself was coined by the British music press around 1970 as a pejorative umbrella for the diverse German underground, and many of the artists it described rejected it, preferring "kosmische Musik" as a description of their work. The label stuck anyway, which is how labels tend to work. What it obscures is the degree to which the scene was not a unified movement but a set of parallel investigations, conducted in adjacent cities, by musicians who shared a historical situation and a refusal to accept the available options. The forty minutes between Cologne and Düsseldorf was not a pipeline. It was a gap wide enough for two genuinely different answers to grow.
