Iain Matheson is a Scottish composer and musician, based in Edinburgh. He writes concert music in the classical tradition. Most of his work is based on some aspect of time, the medium in which music happens. It doesn’t represent programmatic ideas: instead it explores memory, and invites listeners to notice the ways in which time passes. This composition was written for bass clarinet soloist Sarah Watts, who did extensive research on bass clarinet multiphonics. This piece is a great illustration on the integration of multiphonics in contemporary music.
