“Ai Weiwei: Roots and Branches”

The Chinese artist and dissident brings his latest work to New York in this multi-venue showcase featuring a multiplicity of mediums and materials—among them, porcelain, cast-iron, salvaged wood, artist-designed wallpaper and LEGO bricks. Highlights include a massive tree cobbled from dead branches and trunks into a sort of arboreal Frankenstein and an installation of 40,000 teapot spouts broken off and arranged in a circular pile. In these works and others, the artist plays chicken or egg with the relationship between a whole and its parts.
