"The 'soul' of the machines has always been a part of our music. Trance always belongs to repetition, and everybody is looking for trance in life... in sex, in the emotional, in pleasure, in anything... so, the machines produce an absolutely perfect trance."
--Ralf Hütter, 1991, quoted in Kraftwerk: Man Machine and Music
