Born in 1926, the Swiss artist Heidi Bucher is best known for making latex casts of buildings and interiors, works she called “Skinnings.” In 1983, when she was 57, Bucher traveled to an oasis of volcanic rock, the island of Lanzarote, Spain, located off the coast of West Africa. She bought property there and began to do skinnings of her house’s doors. But her final work, made in 1992, the year before she died, was not a skinning. For La Vida El Muerte (Life Death), she filled a cupboard, crudely carved from a tree trunk, with two sacks of Lanzarote’s volcanic ash. One sack was labeled “Life” and the other “Death.” Her son Inigo wondered, “Are these bags a ticket from her own life and death?” At the Red Brick Art Museum, 100 works explore the dizzying creativity of this distinctive artist. —Elena Clavarino
