Em va fer Joan Brossa. The Poetic Revolt, the Social Revolt. In 1947 Joan Brossa met the Brazilian diplomat and poet João Cabral de Melo (1920-1999), then resident in Barcelona. Cabral immediately became friendly with the members of Dau al Set and introduced them to Marxist thought; his aesthetic and political ideas had an especially powerful influence on Joan Brossa, Antoni Tāpies and Arnau Puig. The relationship with Cabral marked an important evolution in Joan Brossa's work from neosurrealism to a critical realism, embodied in the book Em va fer Joan Brossa (Joan Brossa Made Me), written in 1950, and published with a pen-portrait by Ponį and a foreword by Cabral. The Dau al Set group exhibition in the Sala Caralt, in 1951, to which Brossa contributed three object poems -among them the famous Poema experimental (1950) with the hammer and the torn-up card- was to be the group's last unitary act before it dissolved. Brossa, always close to the world of the visual, furthered in his friendship and creative association with Antoni Tāpies and Joan Mirķ. In 1959 he began the Suites de poesia visual (Suites of Visual Poetry). The development and evolution of his experimental poetry were leading Brossa towards visual poetry, the object poem and the installations.
