Moved to respond to the July 1995 Bosnian Massacre, Europe’s worst mass murder of civilians since World War II, acclaimed French multimedia artist Olivier Py created Requiem for Srebrenica, a theatrically riveting meditation on the unfathomable terrors of war. Three women from three generations, dressed in heavy black coats and boots, occupy a starkly industrial steel set. Stand-ins for the thousands of women who lost sons, husbands, lovers, and fathers, they speak harrowing, often numbingly barbaric words from a meticulously assembled pastiche of poems, essays, and news and medical reports. This production, presented in French with English surtitles, is part of BAM’s Next Wave Festival.
