64 student percussionists fill the monumental Kraftzentrale in the Landschaftspark Duisburg Nord with sound. The line-up is reminiscent of a chess board filled with pieces: rules on social distancing are used here to create a visual structure and are needed for all the percussionists to have room in the space. In a composition of space and sound the performers are visible as individuals while simultaneously dissolving into a sound mosaic that covers 400 m². Each percussionist has the same basic kit: a snare drum, a cymbal, wood blocks and a tamtam. As a result of the differences in materials and construction of these instruments, a heterogeneous tutti sound is created that is consolidated into a performance of around 70 minutes by exploring experimental playing techniques, forming groups and solo passages.
