Greenhouse oscillates between participatory performance, workshop and ritual. In times of the 6th mass extinction and enormous social and ecological transformations, the participants gather to learn to let go of concrete or abstract things together. In the spirit of mourning theory, the performance aims to clear the space that is still occupied by losses that have not been mourned. Through the creation of a shared space and with the help of storytelling, singing and somatic practices, practices of grief processing are explored – always in the knowledge that there is no separation between body/mind and body/ecology. The project aims to incorporate specific local characteristics into the project at each performance venue with a local artist or expert and to develop it further. In this way, the performance also aims to explore new forms of touring.
