Acimow Media has wrapped up filming Forbidden Music for Knowledge Network. The feature-length documentary explores Indigenous music rights and ownership, and how Chief Mungo Martin (Kwakwaka'wakw) worked to protect 123 traditional First Nations songs from disappearing through government assimilation tactics. It is the fourth documentary by producer and director Barbara Todd Hager (Métis, Cree). Completing 16 days of filming in Austria, Canada and the United States, Windspeaker spoke to Hager as she entered post-production editing.
