La Moda del Liscio tells a composite story, articulated around major themes (the dance master, the orchestral players, the singer, the club manager, the TV, the epigones of an era) that constitute the epic of ballroom dancing, its anti-heroic dramaturgy, its somewhat vague and kitsch aesthetic. It is a choral story, populated by great figures but above all by orchestras, because ballroom dancing is not a genre for soloists. And there has never been any talk, with regard to ballroom dancing, of 'concerts', but only of 'shows', also choral, each with its own genre dynamics and costumes in which America is always cited. This documentary, through repertoires and interviews, with a focus on the private dimension of those who were the protagonists, wants to reconstruct not a history but a system of memories, an intimate and at the same time public memorial of a country that was happy.
