Lisi and Silvana Natoli founded the group Spazio Zero in 1973. Their work focuses on certain ethnic and historical aspects of Sicily, Sicily being, for them, a microcosm of the Third World. The title of their most recent production, To Salvatore Giuliano, is a dedication to a famous Sicilian criminal. Giuliano began as a rebel, then became the emblem of the revolt of the poor in southern Italy. The American invasion and the collapse of state authority after Italy's defeat in the second World War turned him toward politics. He championed an attempt at secession from Italy, masterminded by the Mafia, who expected to profit by Sicilian independence. The attempt failed, but Giuliano remained linked to the Mafia and was subsequently hired by them to massacre striking farm workers in Portella della Ginestra. The story is treated as a popular myth by Spazio Zero.
