Orchestral Manoeuvres in the Dark (OMD) is a pioneering electronic music duo from Wirral, England, formed in 1978 by Andy McCluskey and Paul Humphreys. Known for blending synthesizers with orchestral arrangements, they achieved massive success in the 1980s with innovative hits like "If You Leave" and "So in Love," becoming influential architects of electronic pop and new wave music. Their distinctive sound and atmospheric production continue to inspire generations of musicians and remain central to the synth-pop genre.
