New Order are an English rock band formed in 1980 by vocalist and guitarist Bernard Sumner, bassist Peter Hook and drummer Stephen Morris. New Order were formed in the demise of their previous post-punk band Joy Division, following the suicide of vocalist Ian Curtis. They were joined by Gillian Gilbert on keyboards later that year. Their integration of post-punk with electronic and dance music made them one of the most critically acclaimed and influential bands of the 1980s.

1985's Low-Life refined and sometimes mixed the two styles, brandishing "The Perfect Kiss"--the video for which was filmed by Jonathan Demme--and "Sub-culture". In February 1986, the soundtrack album to Pretty in Pink featuring "Shellshock" was released on A&M Records. An instrumental version of "Thieves Like Us" and the instrumental "Elegia" appeared in the film but were not on the soundtrack album. Later that summer, New Order headlined a line-up that included the Smiths, the Fall, and A Certain Ratio during the Festival of the Tenth Summer at Manchester's G-Mex.  Brotherhood (1986) divided the two approaches onto separate album sides. The album notably featured "Bizarre Love Triangle" and "Angel Dust" (of which a remixed instrumental version is available on the UK "True Faith" CD video single, under the title "Evil Dust"), a track which marries a synth break beat with Low-Life-era guitar effects. While New Order toured North America with friends Echo & the Bunnymen, the summer of 1987 saw the release of the compilation Substance, which featured the new single "True Faith". Substance was an important album in collecting the group's 12-inch singles onto CD for the first time and featured new versions of "Temptation" and "Confusion"--referred to as "Temptation '87" and "Confusion '87". A second disc featured several of the B-sides from the singles on the first disc, as well as additional A-sides "Procession" and "Murder". The single, "True Faith", with its surreal video, became a hit on MTV and the band's first American top 40 hit. The single's B-side, "1963"--originally planned on being the A-side until the group's label convinced them to release "True Faith" instead--would later be released as a single in its own right several years later, with two new versions.  In December 1987, the band released a further single, "Touched by the Hand of God", with a Kathryn Bigelow-directed video parodying glam-metal. The single reached number 20 on the UK Singles Chart and number 1 in the UK Independent Singles chart, but would not appear on an album until the 1994 compilation The Best of New Order.
