The expression public-population was coined by Michel Crespin, an historic figure in street arts in France. He considers it to represent “members of the public naturally in the street whether or not a performance is taking place. This public represents the broadest possible cultural diversity, with no distinction based on education, role, function, age or social class. Its primary quality is free choice. The choice to walk on by, ignore, stop, watch, listen, or take part, outside of any convention”.
