The Brazilian Campana Brothers are international stars with numerous museum exhibitions to their credit. Surprisingly, this is their first New York solo show. On view is an engrossing array of recent works that veer from more or less utilitarian furniture to purely sculptural pieces. The show demonstrates the brothers’ use of unconventional materials and found objects to dazzling effect. Highlights include a couch incorporating colorful toy alligators, and an enormous mobile made of Brazilian amethyst embedded in large rectangular glass sheets.
