“Masterpieces” is a magnificent journey to 8 of Frank Lloyd Wright’s finest buildings, including such famed structures as Fallingwater and the Johnson Wax Administration building, plus the lesser known gems Cedar Rock, the Stanley Rosenbaum house, and the rarely seen Auldbrass Plantation. The screening (film running time: 95 minutes) is sponsored by American Institute of Architects Southwest Chapter and Monona Terrace.
