Born in Paris, Seth began to express himself on the walls of his city in the mid-90s. His preferred terrain, however, was in the 20th district where he became known in the graffiti scene for his specialization of painting characters.
During the course of his artistic explorations, Seth developed his distinct painting style, working often with the theme of childhood. Using the wall as a blank page, Seth relies on one hand the individual or collective imagination – local gods, myths, or tales. The child becomes a spokesperson, a messenger of his investigations. He puts into play his image of innocence, and places his character in difficult social, political and geographical contexts.
