"Experimentar o Experimental".

An essay is presented on the relationship between avant-garde, marginal culture, and counterculture in Brazil during the military dictatorship from 1968 to 1972, focusing on the works of artist Hélio Oiticica, poet Waly Salomão, and singer Gal Costa. The author explores the origins of the Tropicália movement, which gathered different artistic expressions and social trends among young Brazilians at the time.
