Dam Mantle is the electronic project of Tom Marshallsay from the United Kingdom. Marshallsay starts the project at the end of 2009 after earlier work rooted in post-rock and experimental folk.

The music of Dam Mantle draws on those earlier influences while moving into electronic production. It is described through a broad musical range rather than a single niche, with elements that sit within dubstep, experimental music, instrumental hip-hop and wonky.
