Variations is an electroacoustic sound installation commissioned by the Villa Bernau in Wabern, Switzerland. The original sound installation was created in coordination with the sculptor Wolfram Renger. Renger’s sculptures deal with the historical forming of prisons of cultural and artistic identities. The installation was divided into three spatialized parts. Penalty dealt with the problems of industrial death via the death penalty. Lizkhor dealt with questions of musical/physical closure (via exploring questions of the US prison system) and the relationship of closure to cultural memory. Borders dealt with questions of the limits of closure (exploring European border problems) and its relationship to the forming of cultural identities.
