Artist Hannelie Coetzee presents the second Art/Science #FireGrazer performance at the NIROX Sculpture Park, in partnership with University of the Witwatersrand scientists. This performance entails the live burning of imagery created by Coetzee onto the grasslands, building on the artistic practice of Coetzee which uses art as a tool to communicate complex systems and build awareness of pressing ecological issues. Tribe spoke to Hannelie ahead of this performance.
