Born in Frankfurt, Germany, Flur became the third member of the band in 1973, replacing a drum machine. He was a member of the group from their international breakthrough with the album Autobahn (1974), and remained as they experimented with proto-techno on albums such as Trans-Europe Express (1977) and Computer World (1981).
Frustrated with the half-a-decade it took to produce Electric Cafe (1986), he left the band after the LP’s release — it wouldn’t be until a 2009 reissue that Flur received an artist credit on the album. In 1997, he launched his solo career under the name Yamo and released Time Pie, an album that featured work with the experimental duo Mouse on Mars.
In 2000, he published his memoir I Was a Robot, but the book was pulled momentarily, and re-released with revisions after a lawsuit from the remaining members of Kraftwerk. A 12″ single named after the book appeared in 2004, and it was included on the 2015 release Eloquence: Total Works, a collection of unreleased Flur tracks dating back to 2002.
