New Order are in a class of their own. The Manchester group pioneered the fusion of rock and electronic music. The best example is ‘Blue Monday’ (1983), which the BBC calls ‘a crucial link between disco and house’. New Order rose in 1981 from the ashes of another legend. Joy Division had ended abruptly a year before following the suicide of singer Ian Curtis. The survivors kept on. The quartet continued with their gloomy post-punk but, for balance, listened to cheerful Italian disco. A taste of New York’s exuberant nightlife brought the two extremes together. After ‘Blue Monday’ New Order began making quality synth pop that set the scene for the likes of Arcade Fire, Chemical Brothers and the Pet Shop Boys.
