Katzo/Katsuya Urushizaki began DJing and performing live during his time studying graphic design at Camberwell College of Arts in London. He quickly caught the attention of fellow musicians and event organizers who asked him to play at the club Mass in Brixton as well as local festivals and warehouse parties, such as Douglas Benford’s London-based Sprawl events. Urushizaki soon began producing music of his own. Starting in 2005 he would release tracks on several 12” compilations released by MultiVitamins records under the alias “Katzo.” In 2006 his full length debut album, Disposition, released through Italian label Silentes, featured ten tracks credited to his own name. Also released under his own name in 2006 was his internationally distributed EP for Holland’s Audio,nl label.
