In "The Ghosts Are Returning", GROUP50:50 tells the story of seven "pygmy skeletons" that a Swiss doctor brought from the Congo to Geneva in the 1950s. The artists from Congo, Switzerland and Germany travel to the equatorial forest to meet the nomadic Mbuti people who are threatened by illegal logging and driven out of their territories. Singing and dancing with them, they develop a ritual to allow the seven spirits to find rest. The result is a multimedia musical theater piece about (neo)colonial crimes, death and mourning.

Based on "Hercules" by G. F. Haendel, the Congolese choreographer Dorine Mokha and the Swiss musician Elia Rediger created a post-documentary mining oratorio for 11 Congolese and European musicians, song and dance. They transferred the popular myth into the age of globalisation and transported us with a simple trick from the gloomy present to an obviously better future. Current conflicts over raw materials, corruption, lawlessness, human rights violations and other consequences of global capitalism are settled, compensated and made up for in fiction - a collaborative project for a hoped-for reality and better future.
