Since 1991, the biennial in Lyons has featured the art of both well-known and emerging artists from around the world. Always structured around themes, previous biennials have explored the shifting paradigms of what constitutes art (“Et tous ils changent le monde,” 1993) and showcased work in new media (“Cinema, Video, Informatic,” 1995). For this year’s installment, artistic directors Thierry Raspail and Thierry Prat have engaged legendary curator and Documenta veteran Harald Szeemann for “L’autre,” which examines myriad forms of alterity, otherness, and difference—personal, political, physical, psychological. July 9-Sept. 24
