Here's a concert with a difference: The fifteen singers all have mental health problems. Yet they've recorded a CD and have performed on stage in front of 500 people. Filmmaker Blaise Barrette spent a year with them, filming their confidence-building adventure. From the difficult first singing lessons to the highly successful concert, Ces voix oubliées bears witness to an amazing change in the participants. An inspiring documentary that defies prejudice. In French with English subtitles.
