Mining the Pigeon Audio Visual (PAV), a show that recently closed at the Graham Foundation on February 25th, is a series of 15 slide-tape talks with leading architects selected from the PAV archive of over 200 presentations. In addition to architects, the archive also includes presentations by urbanists, theorists, artists, designers and landscape architects. The tape-slide talks were produced between 1979-1989 and consist of studio sessions with the speakers that were each edited into a 24-slide/30-minute format. Monica Pidgeon, the editor of the prestigious RIBA (Royal Institute of British Architects) and Architectural Design (AD), an influential London-based magazine, developed these presentations to be distributed to libraries and institutions in an era when international travel was less available, difficult and expensive.
