Rolo Tomassi is a British experimental mathcore band from Stocksbridge, Sheffield.
Formed in 2005, they set their local scene alight by playing a synth-driven technical mix of styles and genres difficult to define in a single word. The band's name was taken from the movie L.A. Confidential. They are known for their strong DIY ethic and chaotic live performances.
The band is currently signed to MNRK Heavy. They released two albums on Hassle Records: Hysterics (2008) and the Diplo-produced Cosmology (2010).
