In the installation Post-Production Workshop an artistic residence with guest artists, a workshop with amateurs, an archive of the performances and an exhibition of former artistic research materials were staged and assembled to question participatory modes of movement. The two-day event was a critical reexamination of the physical and theoretical knowledge gained through earlier performances. It used the participants’ physical expertise to reformulate the knowledge towards the question of groove. The movement systems were tested in a series of experiments with regard to their applicability for the understanding of groove in clubs. In the public event framed as an open space installation, audiences and visitors joined the discussion or witnessed the serial movement experiments.
