Blek describes his early work as apolitical, explaining that he just wanted a way to stand out and to free himself from the feeling of anonymity caused by living in a major city. He was the first people to use stencils to make public art on the street using icons instead of writing his name. He started decorating the streets of Paris in 1981 with a rat stencil, hoping to create an invasion of rats – “the only free animal in the city”, while creating a style that would suit Paris and not copy the American style. His street name is said to originate from a childhood cartoon “Blek Le Roc”, also using “rat” as an anagram for “art”.
He studied fine art and architecture at Beaux-Arts in Paris, graduating in 1982. Before his graduation, Prou visited New York City and developed a fascination with the city’s graffiti and street art. “To me, the most interesting aspect of street art is the constant opportunities to be surprised and/or amazed. I lose interest when something becomes routine”.
British graffiti artist Banksy has acknowledged Blek’s influence stating “every time I think I’ve painted something slightly original, I find out that Blek Le Rat has done it as well, only twenty years earlier.”
