Presented now in 4K digitalisation by Cinemateca Portuguesa, this film captured a show at the Coliseu do Porto in 1977. In the year of the 50th anniversary of the Carnation Revolution, we go back in time to feel the weight of the artists who gave their work a political tenor and supported the revolution — like Adriano Correia de Oliveira, José Carlos Ary dos Santos and Carlos Paredes. The film includes a reading of political manifestos from the revolutionary process to date.
