“The world sends us refuse, we reciprocate with music” Favio Chávez says. And this is what he really does. In Asunción, Paraguay’s capital, he conducts an unbelievable orchestra. Young musicians from the Bañado Sur slum, close to the refuse depot of Cateura d’Asunción, have created their cellos from old oil barrels, their flutes from an old water pipe and their violins from tin cans. Trash becomes sound vessels that are played upon for all that they are worth: Mozart, Vivaldi, Haydn, Latin American folk music , Frank Sinatra or Beatles …. and whatever. But certainly never rubbish.
