Stud framing and the unfinished quality. “Buildings that are unfinished look better than buildings that are finished.” Early cardboard (pre-Bloomingdales). Improving the acoustics at the Hollywood Bowl with sonotubes. Frequency response. Question and answer period: climate considerations; reception of chain-link material; Gehry has moved on from using cardboard, chain-link fencing. 16:55 recording of Zambonini talking with students: relationship between drawing and (architectural) reality.
