As host of the weekly radio program Abstract Science since 1997 and Smartbar resident DJ, he is at the forefront of breaking new styles, crossing genre lines and re-introducing forgotten music. When DJing for the dancefloor, Widman mixes a diverse array of sounds–dubstep, techno and detroit electro among them–to create his own form of sonic warfare, designed to both entertain and challenge audiences. This versatility and depth has seen Widman DJ with acts including Amon Tobin, Kode9, Moderat, Monolake, Nightmares on Wax, Plaid and Skream. Widman also records and performs live with Colin Harris as Quadratic.
