1977. Bill Bernstein was on assignment shooting an awards dinner at New York's notorious nightclub, Studio 54. As the dinner ended, the clubbers began to arrive. Short on film, Bill bought ten rolls off a fellow photographer, and stayed for the night. It was the start of a project that, thirty years later, is collected in a book. 'Disco: The Bill Bernstein Photographs' is out now from Reel Art Press.
