Is there an aesthetic to the ‘festival’ phenomenon that exists independently of time and place, music genre and number of visitors? Can the influence of Woodstock, which is often referred to in the media as the ‘mother of all festivals’, be felt at modern festivals such as MS Dockville? Possible answers to these questions are provided by our collective memory: the images. In this compilation, selected photographs from the Woodstock Festival (1969) and the Hamburg festival MS Dockville (2016) search for connections between the two events. The atlas consists of nine double-folded posters that form a booklet when placed one inside the other. By rearranging the pages, different images can be juxtaposed, and new connections and sensory experiences of the ‘festival’ phenomenon itself can be explored. When unfolded, the eight posters can be put together to form a large picture. The picture provides a collage-like overview and records the state of my research. The ninth poster forms the cover and reveals which picture was taken when and by which photographer.
