The centerpiece of the exhibition is Charles Ray’s first work in stone, Two Horses (2019), a relief carved from a single block of Virginia granite. The sculpture is ten feet tall and fourteen feet wide and weighs more than six tons. A smaller work displayed on a pedestal, Mountain Lion Attacking a Dog (2018), is a hypothetical scene from the hills around Ray’s home in Los Angeles. Each animal has been machined from a solid block of aluminum, producing a reflective surface that enhances the work’s finely sculpted details. Two Ghosts is on view through June 22 a Matthew Marks Gallery 7818 Santa Monica Boulevard, Los Angeles. photographs by Oliver Maxwell Kupper
