Earth Workers Requiem/Jubilate is a large-scale musical and visual installation, a joint work by composer Micha Hamel and artist Jonas Staal. The musical composition is inspired by geological time scales of the deep past and the deep future, and consists of a six-hour work for surround electronic music, intersected at regular intervals by instrumental and vocal interventions. The visual installation is a landscape consisting of fossils from deep Earth's past – from motor oil to fossilized ammonites – and images of what will probably form the fossil archive of the future.
