Marmaduke Duke are a conceptual rock duo from Ayrshire, Scotland. It is the side project of the two leading members of Scottish Alternative Rock bands, Simon Neil of Biffy Clyro and JP Reid of Sucioperro. The pair perform under the pseudonyms The Atmosphere and The Dragon when involved in the Duke. Reportedly, the duo formed in 2003, but because of being busy with their own bands, from releasing and recording albums and touring, it took until 2005 for the bands first album (in a trio of concept albums) to be released.
