Au fil du temps builds a picture of an Alpine landscape from a variety of temporal and spatial perspectives. In chronological order, ten scenes present time-lapse sequences captured during the same season in three different locations. The soundtrack may be understood as an extension of this environmental scene but stands out of (the visual) time both structurally and representationally. Structurally, the dominant sound layers resonate with the large-scale rhythms of the environment that are glimpsed in the time-compression of the image sequences (the daily heating and cooling of the earth, and the concomitant effect on weather systems); the moment-by-moment surface details of the scenes are traced only in the video channel. Representationally, the cowbells, which were recorded in the mountain pastures in September and, in iconic musical terms, are a feature of such landscapes-think Mahler (Webern) and Strauss, are out of season with the video. The temporal disjunctions between audio and video (both these sensory channels providing mostly different information) and the spatial disjunction in the split-screen scenes showing synchronous images from two geographically separated cameras combine to provide multiple descriptions of a landscape, while denying the customary correspondence between audio and visual domains.
