In 2008, Jeroen Koolhaas and Dre Urhahn were working on a large mural in the Vila Cruzeiro favela of Rio de Janeiro when a high-end car with dark-tinted windows pulled up. Out got a young man of humble origin who had become famous the world over. Adriano, a global football name was playing for Inter at the time. He had heard strange rumours and wanted to see for himself. What the two Dutch artists had done was turn the long flight of concrete steps that has always existed in Vila Cruzeiro into a river with large carp flying above the waves.
