Playlist of pop songs that have been played by US Army during psychological operations, that are commonly called PSYOP. By blasting the same songs loudly and repeteadly, music and sound provide an insidious tool of torture. This selection was played during Mathieu Copeland’s exhibition, “Studies for a catalogue / a study for an exhibition of violence in contemporary art (1964/2011)“, the 1st of August 2011 at the John Latham Fondation in London.+
