Leo Crossing, A.K.A RoughMath first started out producing for adverts and recording various artists across the music spectrum; Rock, Metal, Indie and Dance. As Dubstep started showing it's face in more peoples lives Leo began receiving more requests to produce Dubstep, Drumstep and Drum & Bass inspired tracks.

After producing bass influenced tracks he then moved into the production of various bootleg remixes in the same style. These remixes included Kate Bush, Placebo, Robyn & Deftones, all of which helped to define his own unique sound.

After establishing his style, in late 2011 Leo decided to turn his hand to his own original material and he also completed an official remix for up and coming producer Koven on his track 'Wake You Up'. - 2 Much Bass

Having the honor of remixing tracks from some of the most prestigious artists in the scene such as Koven & Chrispy, RoughMath proves to be making an impact in the Dubstep movement. The clarity in Leo’s production is immaculate, whilst maintaining dirty, driving bass and drums that pack more punch than Mike Tyson. - Discos Dead Records
