108 (Guido Bisagni) started painting traditional graffiti under several pseudonyms. He was the first writer in Europe to use numbers instead of letters for his name. By the end of the 90s he had evolved both formally and conceptually to become one of the first European post-graffiti artists working with abstract forms. At this time he was painting large and mysterious figures that were invading abandoned spaces. His work has appeared on the streets of Milan, Paris, London, Berlin, New York City, and San Francisco. It is Guido’s firm intention to engage his viewers by make visual chaos, also implementing 3D objects, sounds and installations.
