Born in Poland in 1967, Skki is considered one of the precursors of the post-graffiti movement in Europe. He made his debut on the urban scene in 1983, as a member of the BBC (Bad Boys Crew) trio founded with JayOne and Ash.
Exhibiting in Berlin from 1990, he painted the famous Berlin Wall from 1987 to its fall in 1989. His work rapidly evolved towards ever greater abstraction, so much so that today his work has taken a neo-conceptual and multimedia direction, no longer necessarily aesthetically linked to traditional graffiti.
