Chen's film, which was on view earlier this year in the Albright-Knox's new media gallery, is a meditation on trauma and memory. To make the eight-minute piece, Chen filmed the sites of major atrocities at the Treblinka extermination camp in Poland, the killing fields of Cambodia, the site of the Wounded Knee massacre in South Dakota and the Rwandan countryside. Chen's work, as I wrote in a February review of her Albright-Knox show, "is concerned with the historical residue of human violence" and with "what happens as weeds grow over bloody battlefields and as human memory, a sieve designed to filter out trauma, allows us to forget and eventually repeat our gravest mistakes." Thursday's screening and talk begins at 7:30 p.m. Click here to reserve a spot.
