André is the Swedish-born French artist known by his graffiti alter ego, the top-hatted stick-figure tag called “Mr. A.” His fame on the walls of Paris in the early ’90s led him organically to gallery work, brand collaborations, and life as a creative director and global nightlife entrepreneur. He chooses drawing over classic canvas work, often sketching on scraps of paper or in notebooks, or on signs. His Dream Concertsposters — tempting viewers with all-star lineups never to be seen — have appeared in the streets of Paris, New York, London, and Los Angeles. Those seen here also graced the walls of the Broad Lobby at MOCA in 2013.
