The adventure of a film that uses the real as matter, needs to keep an eye on any detail, any sign that would occur in the course that runs from the first take to the last final choice of editing, because each small event, each causal chain or each flashing chance, will determine the form and content of the film which at the beginning was only a possibility, a simple idea: make a film about the origins of jazz using as a backdrop its most important contemporary expression forum.
