for chamber ensemble, electronics, and lighting

+++

this piece is inspired by the devastating beauty of nacreous clouds. these clouds are both very rare and hauntingly beautiful, with luminous pastel colors streaking across the sky. 

despite their beauty, these clouds are irrevocably harmful to the atmosphere. while their beauty comes from the diffraction of light as it passes through tiny ice crystals in the air, their appearance acts as a catalyst for the reactions of toxic chemicals that deplete the ozone layer and contribute to the ozone hole in the antarctic. 

this piece is a meditation on the beauty and destruction of the world we’re making.

Bára Gísladóttir: Animals of your pasture (2021)

The music begins within a dimly lit room where a ritual is taking place. In a slow procession, a statue is being carried; its belly opens, a flock of birds fly out.
premiered by Riot Ensemble

eroding sky; a new and brighter star | catinblack ensemble | 2025

A body of many bodies; a creature which--

[moans screeches sputters growls squeals howls]

--struggles to understand itself. 

This piece traces the mythic figure of the chimera as a body and a process becoming-with, a site of multiplicity and discovery; a body learning and relearning and unlearning its many selves.
