Assistir Assistir PobreTV. Produced while the Black Audio Film Collective were undergraduates, Expeditions 2 – Images of Nationality is the second of a two-part 35mm slide- tape text entitled Expeditions; part one is entitled Signs of Empire. The work toured England from November 1984 to March 1985, using a Kodak dissolve unit to sequence images into narrative. The soundtrack to Signs of Empire, which consisted of tape loops of musique concrete and political speeches, was amplified to create a powerful environment of dread.
