The US artist Matthew Barney is blazing a trail to Los Angeles this autumn, with solo exhibitions at the Museum of Contemporary Art (13 September-18 January 2016) and Regen Projects Hollywood (11 September-24 October). The Cremaster creator will present a group of cast bronze sculptures at both venues called Water Castings, which evoke “the mythological and material narratives of River of Fundament”, the artist’s back-breaking, six-hour film featuring Maggie Gyllenhaal and the late Elaine Stritch. “Barney made the [new pieces] using a unique process he developed over the past year, in which molten bronze is poured into a pit of bentonite clay silt,” says a press statement. Regen Projects will also show a series of engravings based on the sites and themes of River of Fundament. LA MoCA is, meanwhile, building a special mini-cinema in its Geffen Contemporary space for the Barney smorgasbord (making Matthew’s LA museum debut all the more spectacular).
