European archives hold historical voice recordings that were produced by linguists, ethnologists and musicologists during colonial rule in African countries. While these recordings reverberate with the poly,phonic echoes of colonial knowledge production, to date, acoustic collections have rarely been con,sulted as sources of colonial history. In this book Anette Hoffmann engages with a Southern African audio-visual collection, which is located in five different institutions across Vienna, Austria. Several recordings collected by the anthropologist Rudolf P,ch in August 1908 have been retranslated for this book. These translations provide new insights into P,ch,s collecting expedition to the Kalahari. P,ch,s narrative of his heroic journey is called into question by the Naro speakers, comments, which address colonial violence and criticise the research practices of the anthropologist. By attending to the spoken texts on the recordings and reconnecting them to photographs, ethnographic objects, archival documentation and P,ch,s travelogue, Hoffmann offers a different reading of this research trip into a war zone.triesries.
