Kraftwerk (, German for "power plant") is a Grammy Award-nominated, German musical group from Düsseldorf. The Kraftwerk sound combines a driving rhythm section with catchy, synthesized melodies and harmony; mainly following a classical style of arrangement accompanied by simple lyrics which are sometimes sung through a vocoder or generated by computer speech software. The Moog synthesizer is heavily present in the majority of the group's works, adding to their signature sound creations. In the mid to late 1970s and the early 1980s, the Kraftwerk sound was revolutionary for its time, and it has had a lasting impact across nearly all genres of modern popular music.The Guardian, [LINK: http://www.guardian.co.uk/arts/fridayreview/story/0,12102,1004937,00.html] Desperately Seeking KraftwerkNME, [LINK: http://www.nme.com/reviews/kraftwerk/7663] Kraftwerk : Minimum-Maximum Live
