Still the best-selling 12" single of all time, "Blue Monday" cemented New Order's transition from post-punk to alternative dance with vivid sequencers and a set of distant, chilling lyrics by Bernard Sumner. The single, first released in 1983 though it's been remixed and reissued countless times since, united the group's frequent synthesizer experimentation with an explicit dancefloor aesthetic rooted in electronics pioneers like Kraftwerk as well as the new electro bursting out of New York City. As usual for New Order, the title is never mentioned in the lyrics, which deal with the romantic kiss-off, another constant for the group. Official single reissues followed in 1988 (for the Substance compilation) and 1995 (for The Best of New Order).
