The line-up on this newly released bootleg is said to consist of Florian Schneider, Michael Rother and Klaus Dinger, which tells us that this was probably recorded in that short period of time in 1971, estimated to 6 months, when Ralf Hütter had left the band. Supposedly, the recording was made at the Gondel Kino in Bremen, Germany on June 25, 1971. And it's an interesting recording.
Kraftwerk is a German band formed in Düsseldorf in 1970 by Ralf Hütter and Florian Schneider. Widely considered as innovators and pioneers of electronic music, they were among the first successful acts to popularize the genre. The group began as part of West Germany's experimental krautrock scene in the early 1970s before fully embracing electronic instrumentation, including synthesizers, drum machines, and vocoders.
Beat-Club was a German music program that ran from September 1965 to December 1972. It was broadcast from Bremen, Germany on Erstes Deutsches Fernsehen, the national public TV channel of the ARD, and produced by one of its members, Radio Bremen, later co-produced by WDR following the 38th episode. It is notable for being the first German show to be based around popular music, and featured artists such as The Equals, Grateful Dead, Zager and Evans, Cream, Frank Zappa, The Rolling Stones, Gene Pitney, Ten Years After, Rory Gallagher, Led Zeppelin, Jimi Hendrix, Ike & Tina Turner, The Who, Black Sabbath, Harry Nilsson, David Bowie, The Bee Gees, The Beach Boys, Chicago, The Doors, Kraftwerk and Robin Gibb in its seven-year run. In 1972, it was replaced by Musikladen.
At nearly seven-and-a-half minutes, "Blue Monday" is one of the longest tracks ever to chart in the UK. It has been cited as the biggest selling 12" single of all time by the band and in the film 24 Hour Party People, though this has not been corroborated by any independent sales chart. Despite selling well it was not eligible for an official gold disc because Factory Records were not members of the British Phonographic Industry association. However, the Official UK Chart Company (UK Singles Chart) has estimated its total UK sales at over one million.
