I Track You Sometimes is an open video score of variable duration. It is based on the live video feed of flight-tracking website over a selected area. The video score is overlaid on top of the live flight-tracking feed and is projected to both the audience and musicians. The performers select a plane and track its movements with sound, using a set of simple instructions. The piece is of open length, form and instrumentation.
The sonic translation of the plane movement into a series of sound events directly defines the formal, time-based structure of the piece. This formal limitation imposed by the manual task of following a particular movement of a particular plane forms a constantly changing content of the piece, which directly depends on the commercial flight routes and selected day and area. On the other hand, the nature of the piece might dramatically change depending on weather conditions or unexpected events (such as the grounding of the flight routes in the event of terrorist attacks). In this way, the sonic translation of the flight routes exposes not only the commercial aviation patterns and destinations, but also maps out various micro¯o socio-economic as well as geographic contexts that defines such routes in the first place.
