Deeply linked to the territory of 'Quattro Province' in Italy, Stefano Valla and Daniele Scurati are a direct continuation of the repertoire and the musical language of thefamous 'piffero' players Giacomo and Ernesto Sala. Their activity is aimed at keeping alive the music and culture of oral tradition in this mountainous area and to promote the dissemination through festivals, concerts, workshops and conferences. The duo is pursuing a dual parallel activity playing at parties in the countries of the Apennines, where the dance is still one of the key moments of aggregation (festivities , weddings, festivals, carnivals) and through exhibitions and musical events in Italy and abroad. This is a great documentary. Th duo is filmed at several occasions: parties, at home and in large concert halls. There is also a lot of historical footage and extensive explanations about the instruments.
