Here's another performance of this piece. The program notes for this performance say:

"Simulacrum passes a single melody throughout the different instruments of the ensemble: each musician takes a turn as soloist and temporarily assumes the mantle of authority.  When not featured in a solo capacity, the members of the ensemble act as a 'hall of mirrors' for the soloist, reflecting fragments of phrases, reminiscing past events, and occasionally anticipating changes in melodic trajectory.  A 'definitive performance' is impossible - the formal construct is up to the discretion of the musicians in the moment, ensuring that every presentation is unique."
