The soundscape emerged from our collective hallucinations at the CT3 cooling tower and the reactor building at Satsop Nuclear Power Plant in Washington State, USA. We wandered around and improvised, and the spaces responded with their delays and echoes. Some of the electronic sounds were played back live in the tower with a small 360 loudspeaker – as we improvised to pre-composed phrases. Later Ewa mixed in more electronics for more flavor, and blended it all together.

The Tower of Broken Mirrors (remix 2023)

“Umbrae” was sparked by a glitch of personal memory, seeded by a 1920 poem by Bolesław Leśmian titled “Odjazd” (“Departure”).
I’ve played a perilous game of moving a magnifying glass through my personal latent soundspace. I found it filled with glitches of corroded memories, inaccessible to another human being. A half-forgotten poem escaping translation from the language of my childhood; a disembodied scrap of a musical phrase erroneously preserved by my violinist muscle memory. 
Long dark shadows falling, indefinitely. 
Should one never abandon anything forever?  Is this loss?
 - Ewa Trębacz

The piece is a lamento in the form of a lullaby. It is based on a short fragment of an ancient Sumerian lamentation - one of the five so-called city laments, specifically The Lament for Nibru (Nippur), composed around 1900–1600 BCE.
