Praxis–4 consists of the scenes 22-24 (Meridol, Immer and Vollmond). Inspired by dental work Dietmar Brehm underwent that seemed to take forever, Meridol combines blue tinted 16mm footage of the body, decay and repair. Immer, in turn, takes fifteen different causes of death as its theme, before in the moon-yellow coloured scenes of Vollmond images of a toilet, of Batman and skin diseases emerge from the circular materiality.
