The Tate Modern’s façade, in London, is different. The Museum comissioned six graffitti artists to create site-specific works directly on the river’s façade. They are Gemeos and Nunca (Brasil), Blu (Italy), Faile (USA), JR (France) and Sixeart (Spain).
Unfortunatly, this is the last day of this exhibition, so, if you´re around London Town just move your ass to Bankside London SE1 9TG and check it. I loved it :)
