Didier Jaba Mathieu puts color on the campus of Sart Tilman! Since Tuesday, the graffiti artist is in full work on campus: he produces a fresco of 11 meters, which completes a first work created in 2015. The whole comes to enrich the collection of the Open Air Museum of Sart Tilman, who set up this collaboration. Jaba is an exceptional street art artist. With his color bombs, abstract shapes and lettering, he builds a universe inspired by cinema, science fiction and futuristic megacities. Born in Colombia, having spent his adolescence in Liège, Jaba has been living in Singapore for about ten years. A graffiti collector, he leads an international career and contributes to give his nobility to urban paintings.
