Nacha Guevara (Mar del Plata, 1940) is an artist inextricably bound up with the memory of the Torcuato Di Tella Institute, combining mass appeal and avant-garde experimentation. Her shows Nacha de noche [Nacha by Night] and Anastasia querida [Beloved Anastasia] established her as one of the first Argentinian performers to venture into protest song, blending an incisive repertoire with unconventional theatricality against the rebellious cultural backdrop of the 1960s. Her songs were biting attacks on the institution of the family, gender roles, female submissiveness (‘Don’t marry, girls, don’t marry,’ she ranted in her cover of the Boris Vian penned number ‘Ne vous mariez pas, les filles’) and the dominant moral order (‘We’re the guerrillas of the new song / We hate war and injustice / Not like you, bourgeois!’). Her repertoire set songs by Jorge Schussheim, Mario Trejo and Jorge de la Vega alongside the Paris of Georges Brassens or the Berlin of Kurt Weill in an absurd yet urgent and defiantly testimonial tone. After the first collective threat issued by the Triple A (Argentinian Anticommunist Alliance) against cultural workers, Nacha Guevara went into exile in Mexico and later lived in Spain, Peru, Brazil and the United States. After her return to Argentina in 1984, she established herself as a towering presence in Latin American show business.
