The Swiss bad-boy artist inaugurates yet another Gagosian Gallery uptown, and fills a temporary Gago annex on the LES, with work derived from a project that was part of his 2013 retrospective at the Museum of Contemporary Art, Los Angeles, and the Geffen Contemporary at MOCA. It was at the latter space that he enlisted more than a thousand volunteers to create a wild, rambling installation of clay sculptures. The participants ranged from local elementary-school students to professional ceramicists, who, working in shifts, modeled the objects on the spot, creating an anarchic array of figures in differing scale—everything from Jabba the Hutt to slices of pizza. Fischer culled some of these pieces, giving them the permanence of cast bronze. His show downtown features a selection of figures—a mermaid, a Pietà, a guy having sex with a pig—while uptown, a single large work, a life-size rendering of the Last Supper, takes up Gagosian's new storefront on Park Avenue.
