Eira is an Expanded Audiovisual Format (EAF) work for fulldome projection and multichannel audio. The shape of the work is derived from data concerning loss of global glacier mass since 1945. The work is palindromic, showing the initial contraction of glacial mass over the past 80 years, before showing the process in reverse as a call to try and reverse some of the damage done to our natural world. The composition is a combination of direct data audiovisualisation of glacial mass loss, alongside composed sonification using recordings of glacial calving and field recordings from rivers and streams in northern Scotland. It works best in multichannel format – originally it was composed for 52.1, but works well in 10.1 or 6.1 where possible (much of the complex beating between close frequencies is lost in stereo format).

Eira was selected for the ISCM World New Music Days Scottish Section Shortlist 2026 – more details here.
