Christopher Mercer, more commonly known as Rusko, is an English dubstep record producer and DJ.
Influenced by a musically affluent family, Rusko graduated from Leeds College of Music with a degree in Music Production. Immersed in the world of Dubstep through Leeds based event "Sub Dub" and the closely connected Northern counterpart of Digital Mystikz "DMZ" events, which are both held at the West Indian Centre, Rusko moved to London to work with the record label Sub Soldiers, and connect with now associated act Caspa.
Rusko made his production debut in 2006 on Dub Police with the song SNES Dub. By 2007 he released Babylon, Vol. 1 with Sub Soldiers. Steering away from the darker side of Dubstep, Rusko brought an upbeat sound to the scene that appealed to many outside the community. Rusko's extremely successful hit Cockney Thug has appeared on various DJ sets and mixes including Pete Tong, Switch, M.I.A. and Santogold. His music has been remixed by artists Buraka Som Sistema as well as Drop the Lime, Scratch Perverts, Sub Focus and fellow act Caspa. Rusko also did his own productions and remixes of artists like Adele and A-Trak featuring Kid Sister.
