The Museum of Contemporary Art’s Geffen Contemporary presents Cai Guo-Qiang: Sky Ladder, the first West Coast solo exhibition of the New York-based artist known for his gunpowder drawings, installations and “explosion events.”A versatile artist, Cai Guo-Qiang uses different materials and art forms to visualize the invisible forces in nature in imaginative and playful ways. “Cai Guo-Qiang fuses historical references and a futuristic vision to create art that is totally contemporary,” says MOCA director Jeffrey Deitch. “His work engages his audiences both experientially and visually. It is spectacular but also intimate.” A public outdoor explosion event, titled Mystery Circle, takes place on April 7, with special pyrotechnics creating art on the exterior wall of the Geffen Contemporary; the exhibit formally opens on April 8. In addition to the explosion event, Sky Ladder features other new works commissioned by MOCA, including three gunpowder drawings. 152 N. Central Ave., downtown, 213.626.6222. moca.org
