The first Situationist text to be published in the UK in 1974, ‘Leaving the 20th Century’ was Chris Gray and the English situationists’ attempt to capture and distil the vibrant anti-art, anti-capitalist energy of the original International Situationist texts (1957-74). With its loose translations and irreverent commentary, Gray and co. attempted to capture the “terrorism, wit and general megalomania” of the original publications, whilst faithfully reprinting the “photographs of girls, soldiers, bombings, comic-strip frames, maps of cities and diagrams of labyrinths, cathedrals and gardens.” From the art/anti-art beginnings, to the role of the Situationists in the worker-student insurrection of May 68’, ‘Leaving the 20th Century’ remains the definitive English pro-situ text.
