In this absurd and forceful play, two brothers, one weak, one strong, play out a primal scene of envy, cruelty and torture as the strong exerts his power and aggression over the weak. Involuntarily, the audience finds itself complicit in the brutality witnessed onstage through Gambaro's command of a powerful and irresistible black humour. Here the absurd becomes a harrowing metaphor of the most pure and raw reality. First performed in 1967, this is an early, yet startling brilliant, work by the internationally acclaimed Argentine playwright, Griselda Gambaro. Siamese Twins runs at Theatro Technis , London, 7-25 September 2011.
