Threshold is self-perpetuating system for sound and action in a social space. Performed at the High Zero Festival in 2008, this piece involves musicians, servers and diners. The ordering of specific foods triggers specific sounds which, in turn impacts the way in which food is served. Also involved is a “manager” who directs the servers to behave in various ways based on hand gestures. The result is a dining event in which not everyone ends up getting what he or she ordered. The social convention of dining out is shaped by the composition of elements in this work.
