===Tour===
At the end of 1974, Kraftwerk had a short tour in West Germany; where the group remained a quartet, retaining Wolfgang Flür and hiring [[Karl Bartos]], who replaced Roeder in the group.{{sfn|Bussy|2004|p=56}}{{sfn|Bussy|2004|p=63}} Bartos was a 22-year old music student at [[Robert Schumann Hochschule]], Düsseldorf, who was hoping to become a percussionist with the [[Berliner Symphoniker|Berlin Symphony Orchestra]]. Bartos had played percussion at concerts in Germany with works by [[Karlheinz Stockhausen]] and [[Mauricio Kagel]].{{sfn|Bussy|2004|p=64}} Kraftwerk toured the US for three months, starting in April 1975.{{sfn|Bussy|2004|p=65}}{{sfn|Dalton|2004}} The US tour was followed by a seventeen-date tour of the UK in September. Bartos noted poor ticket sales for the British shows, recalling the group played to mostly empty halls in [[Newcastle-upon-Tyne]], London, [[Bournemouth]], [[Bath, Somerset|Bath]], [[Cardiff]], Birmingham, and [[Liverpool]].{{sfn|Schütte|2020|p=72}}

During the tour, the material consisted mostly of music from ''Autobahn'' and some of their earlier material. The group had difficulties with their initial road crew, who were fired and replaced during the American tour.{{sfn|Bussy|2004|p=65}} Issues also arose with the group's equipment; synthesizers had to be turned on in the afternoon to be tuned for the evening, and lighting from rigs was strong enough to put the instruments out of tune.{{sfn|Bussy|2004|p=66}}{{sfn|Bussy|2004|p=67}} They also experienced problems with the differences in [[mains voltage]]s between countries.{{sfn|Bussy|2004|p=66}}
