The archaeological record of the Upper and Epi Paleolithic has produced several objects with sound-producing potential of the aerophone type, interpreted as bullroarers. Recently a similar implement was identified in the Later Stone Age of the southern Cape, in the Matjes River Wilton layers. In this paper we present a depiction from the Cederberg showing a group of eight human figures, each playing what morphologically resembles bullroarer aerophones. Using digital image recovery techniques we could ascertain sufficient detail to replicate these instruments and record their sound. Using the same digital methods we conclude that the group scene is a palimpsest of two painting events, thematically and spatially connected although separated in time. The sound-producing qualities of the replicated instruments are assessed through actualistic and experimental research. Results are evaluated with reference to our earlier analysis of ethnographic and archaeological aerophone models recovered in the region.In previous work we linked ASC (altered states of consciousness) and ESA (enhanced states of association) to the sounds created by aerophones. In this study we consider aspects of topography and landscape, contextualized within a time-frame provided by the archaeology of the Doring River valley and environs. We suggest that the painting and the sound-making depicted is most likely related to ‘working with rain’, an intervention aimed at influencing !Khwa and the hydrology in the arid Karoo region.
