Oscar Niemeyer's Modernist landmark Edificio Copan was the largest residential building in Latin America when it became part of Sao Paulo's skyline in 1966. In a project that's as much sociology as art, Berlin-based artist Peter Freidl interviews some of the 107 full-time employees whose lives are occupied with keeping this vertical utopia running. The scale is tremendous - the building has over 60 doormen alone, and employs firefighters, masons, electricians, secretaries and managers, among others. Friedl asks them about their work and their lives outside work, trying to paint a picture through first-hand accounts of the complex urban social reality of a Brazilian megalopolis.
