Marmaduke Duke is a Scottish conceptual rock duo from Ayrshire, formed in 2003 by Simon Neil, frontman of Biffy Clyro, and JP Reid, frontman of Sucioperro.[](https://www.allmusic.com/artist/marmaduke-duke-mn0000525799) [](https://www.discogs.com/artist/1382171-Marmaduke-Duke)
The project draws inspiration from the theatrical prog rock of the early 1970s, blending alternative rock, indietronica, and post-hardcore elements into a surreal, narrative-driven sound.

Marmaduke Duke has released two studio albums to date: The Magnificent Duke in 2005, an 18-track collection of eclectic songs, and Duke Pandemonium in 2009, which features a more polished production with singles like "Rubber Lover" and "Silhouettes."
