Gabriel Orozco's Asterisms is a two-part sculptural and photographic installation comprising thousands of items of detritus he gathered at two sites - a playing field near his home in New York City and a coastal wildlife reserve in Baja California, Mexico. Presented as a taxonomic study of material, shape, size and colour, the exhibition highlights Orozco's subtle practice of subjecting the world to personal, idiosyncratic systems while invoking several of the artist's recurring motifs, including the effects of erosion, the poetry of the mundane, the relationship between the macro and the micro, and the tension between nature and culture. Nancy Spector, Deputy Director and Chief Curator of the Guggenheim Museum, contributes an essay to this richly illustrated volume.
