Rolo Tomassi are a band from Sheffield, England. Their name is taken from the fictional character Rollo Tomasi in the film LA Confidential. The band formed in 2005 and set their local scene alight by playing synth driven technical hardcore.

The band self-released their first demo shortly after forming. Shortly after the band pursued a tape release via danger!laser!phaser!razor! where only 200 copies were made. After a split EP with Mirror Mirror the band signed to Holy Roar records after building up a reputation for a fearsome, energetic live show. With Holy Roar the band released their most famous release to date, Their self titled EP. This EP featured re-recorded songs from previous demos and EPs amongst newer songs. To support this EP the band toured up and down the country numerous times, mainly supporting bigger bands such as I Was A Cub Scout and 65daysofstatic. In June 2008, Rolo played a very well received show at Download Festival.

Currently the band have signed to Hassle Records, and released their debut album, entitled 'Hysterics', on 22nd September 2008.
