The work of Mario Garcia Torres traces and restages half-hidden histories and lost moments. For example, the slide piece What Happens in Halifax Stays in Halifax (In 36 Slides), 2004–2006, explores the aftermath of a “secret piece” by Robert Barry, executed by students in Halifax in 1969; neither the black-and-white images nor the subtitles give direct clues as to the nature of this piece, which only exists, if at all, in the participants’ memories.
