There is that joke in Only Fools and Horses where Trigger gets an award from the council for saving money by using the same brush for 20 years. 'This old broom has had 17 new heads and 14 new handles in its time.'
By the same token the line up of Kraftwerk has changed over the years but so anonymous are the members of the band that only the fervent fan can tell who even the long established ones are. The new replacements are probably manufactured in some factory in Rhineland.
The only other constant about Kraftwerk is that no documentary about the band mentions their number 1 single in the UK, The Model. It seems they are probably embarrassed with their hit record and sometimes at a push, their other hit single Tour de France gets a mention as it does here.
This documentary tells the the story of the reclusive German electronic/techno/industrial experimentalists called Kraftwerk who according to the journalist Paul Morley have been more influential that the Beatles.
It features the band performing live tracks filmed at their Tate Modern shows in London in February 2013 mixed with expert analysis and archive footage of the group going back to 1970 when they were long haired rockers with real instruments.
Enthralling to anyone who wishes to know more about the band and their legacy. Non fans will be left none the wiser. They can get on their bikes as members of Kraftwerk usually do.
