When riding around in Barcelona, color often bursts out of the blue, right before your eyes, whether on a wall, in an advertising display, down on the pavement or hanging on a lamppost. The work of urban artists is unpredictable, direct and provocative. Sometimes it makes you smile, often it stimulates you, and yet it can make you wonder about what you see for a couple of minutes while driving or walking. Keith Haring’s mural was the first one in Barcelona. Created way back in 1989, it was a project against AIDS in the Raval district, but many other international and local artists like Fontcuberta, Binty Bint, El Xupet Negre, Kenor, Aleix Gordo, Invader and Axe Colours have also left their mark on the city in the last few years. Like other Western cities, Barcelona is a huge canvas for those who have something to express. The urban habitat is the best art gallery. Keep your eyes wide open and look around.
