Baltimore-based experimental electronic duo Matmos have never shied away from a concept. They originally rose to prominence in the late ’90s with their predilection for deconstructing “found sounds” into dance music far too intelligent to be categorized as simply “IDM.” Their 2001 album, A Chance to Cut is a Chance to Cure, was an epiphany, taking sounds from the operating theater to create a visceral meditation on plastic surgery. Two years later, they returned with The Civil War, their most gorgeous album, exploring the sounds of historical folk music. In the time since, the music of M.C. Schmidt and Drew Daniel has gotten increasingly more cerebral, even more experimental, reaching an apex in 2013 with The Marriage of True Minds, a markedly conceptual album based on four years of parapsychological experiments.
