Some will hate it. Some will love it. Many will be confused. More to the point, it’s creepy AF! But “The Theater of Disappearance,” a recently opened exhibition by the Argentine artist Adrian Villar-Rojas at the MoCA Geffen Contemporary in Los Angeles, is a stunning, ambitious, intriguing and unsettling show on a massive scale and must be seen. Or rather, it must be experienced. The exhibition amounts to a giant art installation of geological and human cultural artifacts presented in some post-human future. Villar-Rojas presents stark vision of humankind’s legacy that is fascinating and terrifying.
