In "Ionization Music," a Cold War-era Civil Defense Geiger counter detects the radiation emitted by a sample of Trinitite: desert sand from the Tularosa Basin in New Mexico, melted into glass by the world’s first nuclear explosion in 1945. The iconic “click” of the Geiger counter is processed electronically into a dense soundscape that is varied, spatial and musical but inherently unpredictable and arhythmic, reflecting the temporary rise and fall of radioactivity in harmony and discord.
