Venturi was engaged in the Philadelphia Orchestra concert hall for about a decade while the proposal tried to attract funding. Eventually, Venturi, Scott Brown & Associates was, in effect, dropped.

How is it possible that Philadelphia let Venturi and Scott Brown slip through its fingers without ever having extracted from them a large, public downtown building?
