Four videos about artistic interventions in public spaces. Brad Downey’s Public Discourse is about New York graffiti art. Though somewhat bland in form (interviews with the artists followed by zoom shots of the art), it covers more than just spray-painting taggers: one artist installs abstract metal sculptures; another paints miniature landscapes over signs. Igor Vamos and Melinda Stone’s Suggested Photo Spots follows members of the collective Center for Land Use Interpretation as they install “Suggested Photo Spot” signs in a variety of locales. While parodying similar signs erected by Kodak at scenic sites, the group invites an aesthetic reassessment of disregarded aspects of our landscape, including a toxic-waste dump and a Wal-Mart distribution center. 65 min.
