Our music feature today is about the songs that have been the voice of protest all over the world.
Our guest is Matariki Williams - curator of Mātauranga Māori at Te Papa Museum in Wellington.
She's co-authored a book - Protest Tautohetohe: Objects of Resistance, Persistance, and Defiance - it's a book about protest in New Zealand, from wars, to trade union action, and protests against apartheid.
