Chris Bowlby profiles Ralf Hutter, the only founding member left of the German electronic band Kraftwerk. Coming from an obscure industrial background, Kraftwerk first formed in 1970, and are now credited with being hugely influential on a host of musicians and on music of diverse types, including electronic, hip hop, house and drum and base.
Notoriously uncommunicative with the outside world, Kraftwerk used to only have a fax machine as a point of contact at their studio though Ralf Hutter says even that has now gone.
Krafwerk have just completed a major series of concerts in New York and are promising that they will be releasing a new album "very soon" - the first in nearly a decade.
