Once again, Palau Vincles Fest is the end-of-year concert of the choirs of the Palau social project, where the winning songs of the Palau Vincles Summer Song choral composition competition, which is now in its fifth edition, will be premiered. Hundreds of children and young people will perform on the modernist stage representing the different Palau Vincles centres and others who have been invited, in an event open to the singers' families to enjoy the music and which represents a demonstration of the opportunities that choral singing offers as a way for social transformation.
