Twenty years ago, David Kramer embarked on a quest to track down several self-taught folk musicians in the arid regions of the Karoo and Northern Cape. This led to the Karoo Kitaar Blues concerts. Unique voices such as those of Helena Nuwegeld, Hannes Coetzee, Tokas Lodewyk, Koos Lof and Siena Mouers moved audiences, often to tears. Photographer John Hogg photographed these concerts and artists at the time – most of them have since passed away. The photographs, which have never been exhibited before, tell moving stories of a rich tradition; of people who never dared to dream of fame, but learned to sing to drive away the cold and darkness.
