The Luce Institute Archive celebrated 90 years of existence in 2014. To celebrate, nine of the most promising directors of Italian cinema made short documentary films from the institute’s collection. Alice Rohrwacher is one of them and her work talks about music, memory and war with Una Canzone.This short film is a mid-career work commissioned by Istituto Luce on its 90th anniversary and one segment of the documentary 9x10 novanta. Una Canzone recovers the lost art of singing through an ever-surprising montage of archival footage. Where did you learn the songs you know? Who taught you? These are the questions Rohrwacher posed in her neighbourhood, combining the answers with archival material from Luce Cinecittà.
