“Border Cantos,” a unique collaboration between American photographer Richard Misrach and Mexican American sculptor/composer Guillermo Galindo, uses the power of art to explore and humanize the complex issues surrounding the United States-Mexico border. It's presented now through April 24 at Crystal Bridges Museum of American Art in Bentonville, Arkansas. Richard Misrach, who has photographed the US/Mexico border since 2004, documents landscapes and objects, including things left behind by migrants. His large-scale photographs, along with grids of smaller photos, highlight issues surrounding migration and its effect on regions and people. Responding to these photographs, Guillermo Galindo fashioned sound-generating sculptures from items Misrach collected along the border, such as water bottles, Border Patrol “drag tires,” spent shotgun shells, ladders, and sections of the border wall itself. The sounds they produce give voices to people through the personal belongings they have left behind. Presented in English and Spanish, “Border Cantos” offers perspective on the challenges of migration, inviting us to bridge boundaries. “Border Cantos” premiered at the San Jose Museum of Art and then traveled to the Amon Carter Museum of American Art, Fort Worth, before it arrived at Crystal Bridges. Admission to Border Cantos is free, but tickets need to be reserved at http://crystalbridges.org/exhibitions/border-cantos, or call (479) 418-5700.
