81.92: "A l likeness is a gift... it avoids... or confuses time if your prefer." said John Berger. Following this premise, 81.92 is a structuralist inquiry into the notion of presence and absence as it reveals archival radio broadcasts from former Montreal radio host Mike Wolkow. The former (the audible) is left invisible while the later (the visible) seeks to find the missing elements that trace the passage of this vocal presence. Past and present interplay in this piece that shifts between epochs, thus mimicking a radio signal that is being tuned in.
