Former warlord's musical mission

Available for over a year

Joe Wylie was granted amnesty for his role in Liberia's armed conflict over three decades. He now uses these experiences to lecture on peace at universities across the country. Another of his pastimes is music, using an ancient stringed instrument played with the teeth and hands to produce melodies which evoke the sounds of village life.
