BLU is a innovative street artist whose work in large scale formats often has an allusion to a larger social-political commentary. While some of his work is ambiguous, and reminiscent of the black and white drawings of Edward Gorey, most of his work requires a bit of thought and introspection, and strikes us as a cross between Art Spiegelman and Banksy. This home site for his work is a great all-in-one destination to view all of his work. Also don't miss his one-of-a-kind graffiti animation MUTO (for video, scroll down).
