Q&A: Danilo Maldonado Machado, the dissident artist called 'El Sexto,' on art and liberty in Cuba

At the tail end of 2014, Danilo Maldonado Machado, the graffiti artist known as “El Sexto,” was detained by the authorities as he made his way to a public park in Havana to stage a work of protest art. In his vehicle, he was carrying a pair of pigs that he had painted with the names of the Castro brothers — one “Raul,” the other “Fidel.” His plan was to release them and let members of the public catch them and take them home.
