Local Equilibrium Dynamics is a work for two musicians, working both within and around a single piano. These sounds are processed in real-time both algorithmically by the computer, and by a small chamber ensemble of electronic musicians. The duo performs a number of interactions throughout the piece, including collaboration, disruption, and dispersion of the sound each produces. The live processing complicates this relationship even further as the sound is transmitted to the audience. As these two musicians perform within such an intimate space, they variably help and hinder each other as the work progresses. This creates increased moments of tension in both the musical output and the performance dynamic between these two musicians. The title refers to a principle in thermodynamics, whereby the thermal state of a system can be determined if the variations within it happen slowly enough in space and time. This concept serves as a metaphor for the system formed by the interplay between the two performers and the live processing.
