Orchestral Manoeuvres in the Dark

Context: Critic Hugo Lindgren wrote that OMD have cultivated a "legacy as musical innovators". In February 2007 a Scotsman journalist said: "If Kraftwerk were the Elvis Presley of synth-pop, then Orchestral Manoeuvres in the Dark were its Beatles." In 2008, American publication The A.V. Club noted that McCluskey and Humphreys were "often labeled as the 'Lennon-McCartney of synth-pop'." In a 2008 piece on OMD, The Quietus magazine editor John Doran called them "the only Liverpool band to come near to living up to the monolithic standards of productivity and creativity set in place by the Beatles", and asserted: "Orchestral Manouevres in the Dark are not one of the best synth bands ever: they are one of the best bands ever." Veteran BBC DJ Simon Mayo described OMD as "the fathers of electronic music in this country [the UK]."  OMD's experimental brand of synth-pop has garnered limited mainstream attention. The group generally eschew choruses, replacing them with synthesizer lines, and opt for unconventional lyrical subjects such as war and machinery; the BBC wrote that "OMD were always more intellectual" than "contemporaries like Duran Duran and Eurythmics". The band also rejected celebrity status and strove "to have no image". Despite the group's experimentation, they had an established knack for pop hooks; AllMusic critic Mike DeGagne wrote that OMD's music was "a step above other keyboard pop music of the time, thanks to the combination of intelligently crafted hooks and colorful rhythms". DeGagne's colleague Jon O'Brien remarked that the outfit were "ahead of their time".  McCluskey in 2010 opined that OMD had become "the forgotten band" (he had predicted in 1981, at the peak of the group's popularity, that they would soon be forgotten). The band have nonetheless earned a growing cult following. OMD have come to be regarded as one of the great Liverpool acts of the 1980s, and pioneers of the synth-pop genre. Architecture & Morality (1981), regarded as the group's seminal work, had sold more than 4 million copies by early 2007; Sugar Tax (1991), the album that marked a commercial renaissance for the band, had sold more than 3 million by the same time period. The experimental Dazzle Ships (1983), while not as commercially successful, has retrospectively been praised by critics, according to The Oxford Times and Fact. OMD's overall record sales stand in excess of 40 million.  The group regularly features on 1980s compilation albums and box sets; multiple OMD tracks feature on each of the three volumes of Ministry of Sound's Anthems: Electronic 80s series. The band's songs (and samples of their work) have featured in films such as Urgh! A Music War (1982), Weird Science (1985), Pretty in Pink (1986), Arthur 2: On the Rocks (1988) as well as in television shows including Scrum V, Ashes to Ashes, Top Gear, Chuck, Cold Case, Modern Family, The Goldbergs and Castle. Cover versions of "If You Leave" have appeared in the film Not Another Teen Movie (2001) and the TV series The O.C.; a season 6 episode of Degrassi: The Next Generation was named after the track. The 2015 film Ex Machina also incorporated their song Enola Gay. Additionally, every episode of the TV show Hunters is named after an OMD song. CANNOTANSWER
