The June 4 presentation was a part of a book tour. Both Isenberg and Gehry were on stage, as well as the GRI moderator Wim de Wit. The previous appearance of Isenberg and Gehry was at the New York Public Library on May 13.
The interesting thing was that on both occasions Gehry with visible pleasure talked about “The Simplsons” episode, in which a famous architect “Frank Gehry” gets a letter from Marge who wants him to design a concert hall for Springfield. Gehry crumples the letter and tosses it on the ground then looks at it and says: “Frank Gehry you are a genius.” The construction process, as you can see in the pictures, involves a wrecking ball.
I discussed the theme of violence in Gehry's designs in the article "Modernism and Destruction in Architecture."
