Sound installation at C.P.C.A.
Austrian artist Franz Pomassl transformed the acoustic, spatial and physical experience of the rooms located in the ground floor of the C.P.C.A. Trial Error consisted of a 76.42 minute musical compact disc, filled with "feedback", system failures and free-moving rhythms and effects produced by the acoustic machine itself, that the human ear cannot detect. Only amplifiers and loudspeakers were visible.
