International Award winning Death Metal Angola follows a loving Angolan couple, Sonia and Wilker, whose love for death metal music is bringing hope to the town and children of Huambo and Angola as a country. The devastating reality of Angola’s history of wars and civil unrest has left the country’s people torn, broken, and starving for something to give them peace. Sonia and Wilker’s dream to put on the first national rock festival ignites the emotions of the Angolan people, and helps them heal from the war-stricken path Angola has left behind. This engaging reality of Angola touches the heart of the viewer and sheds new light on a music genre that is not well understood.
