Orchestral Manoeuvres in the Dark (OMD) are an English electronic band formed in Wirral, Merseyside, in 1978. The group consists of co-founders Andy McCluskey (vocals, bass guitar) and Paul Humphreys (keyboards, vocals), along with Martin Cooper (various instruments) and Stuart Kershaw (drums); McCluskey has been the only constant member. Regarded as pioneers of electronic music, OMD combined an experimental, minimalist ethos with pop sensibilities, becoming central figures in the late-1970s/early-1980s emergence of synth-pop.
