Ladytron are a real oddity of a band, made up of two Liverpool DJ's and a couple of disaffected, enigmatic chanteuses dressed in black retro-chic. The electro-pop produced by this quartet is truly intriguing, full of harsh, ominous industrial sounds backed up with vocals of blank, emotionless austerity. Stylistically it owes more than a passing debt to the sound of Kraftwerk, and at times is just a little too kitsch for its own good. Taken as a whole, however, 604 amounts to a gloriously inspired vision of the future, a world where the thrills of glamour are offset by a deadening sense of alienation.
