1 Dec-6 Feb 2005. This exhibition at the CaixaForum presents 150 "unauthorized" photographs taken by a Chinese photojournalist during the terrifying years of the Great Proletarian Cultural Revolution (1966-1976). Li Zhensheng, who worked for 20 years for the Heilongjiang Daily and who risked his life to catalogue the collective madness that gripped Communist China during that period. The photos include the peoples courts, the humiliations, beating and ridiculing of victims in public, as well as the personality cult of the leaders. There are a number of graphic records of the frequent mass executions and firing squads that took place. The 150 works featured, a small but representative selection of the 30,000 shots hidden by Li Zhensheng under his floorboards, offer a fascinating and sinister glimpse of one of the 20th centurys most violent and regrettable episodes. With the intention of delving further into Zhenshengs reflections on the Cultural Revolution, CaixaForum is screening two films and two documentaries and organising a conference with the participation of the photographer.
