Rap group fights for indigenous rights in Chile Performing to around 100 people in a Santiago park, rap band "Wechekeche Ni Trawun" is using music as a peaceful way to fight for the rights of the Mapuche indigenous community. Wearing traditional bandanas in the "Trarilonco" colors, three of the band's members beat out the rhythm with their "wada" instruments, a form of Mapuche maracas.
