Bill Morrison/Michael Gordon:Decasia: A State of Decay (Plexifilm). Avant-garde filmmaker Bill Morrison created this film by editing found archival footage whose emulsion had deteriorated over the years; he loops and overlaps it, and the visual crud interacts with itself. But the found images are often still recognizable, so the result veers from the purely abstract to a barrage of new combined realities. Significantly, he’s edited his images to the score (and not vice versa, which is normally the case); the accompanying soundtrack is by Michael Gordon, whose propulsive 55-piece ensemble of detuned strings and prepared pianos is a perfect analogous fit for Morrison’s imagery of birth scenes, walks among the ruins, earthmovers, ocean liners, ancient nuns, seemingly doomed children on the school bus. The combined effect of sound + image in Decasia feels like a privilege, a visit to another creepy world, where you see again the potentialities and dangers of your own world way back home.
