Marmaduke Duke are a conceptual rock duo from Ayrshire, Scotland, comprising Simon Neil of Biffy Clyro and JP Reid of Sucioperro. Within the band, the pair perform under the pseudonyms The Atmosphere and The Dragon. According to Neil, the band, and its albums, are "based on a trilogy of unreleased manuscripts that a friend of ours bought to this country a few years ago. We're really just working to soundtrack those stories."
