The synthesizer trio QRM are back with a set of live electronic instrumental pieces on the theme of the deep ocean. You will be treated to music inspired by everything from early life in the oceans to current day marine research, and everything in between, played on a variety of replica vintage and modern electronic instruments. The performance is once again accompanied by a video created by visual artist and composer Hilary de Vries. At the end there will be time to ask questions and have a look at the kit that the group use.

The Lindsay System began with a question: could the familiar range of the Scottish smallpipe chanter be extended without adding keys or losing the character of the traditional instrument? Donald WG Lindsay traces the development of the system through twenty years of experiment, invention and musical practice. Then comes a concert set played on the resulting extended-range smallpipes, revealing the musical possibilities that emerged from the design.

The Mearns Singers (conductor Irene Watt) are a community choir from the land between the Grampians and the east coast of Scotland, a landscape of rolling fertile farmland, with coastal villages with a fishing tradition. One of their songs is based on Sunset Song, while others come from the sea, among them the Unst Boat Song and Partans in his Creel, and there are songs from other lands as well.

After the concert, Twa Folk (Irene Watt and Graham White) welcome you with music and song from the North-East of Scotland. They welcome too some of the visiting musicians and singers who are in Orkney for the festival.

How do memories make us who we are? Music and poetry meet neuroscience to seek the answer, with voices and strings woven together to explore the richness and strangeness and beauty that builds from our earliest moments of life. Orkney Camerata String Quintet is joined by soprano Hannah Firth in a work by composer J. Harry Whalley, with speakers Flora Munro and Adam Zeman. The words are by Adam Zeman and Alexander McCall Smith, and the performance is conducted by Peter Nelson.
