Hear how gravitational waves tell us of events far across the universe – and then get into the pool and enjoy music and sound art which can be heard both above the water surface and below. With audiovisual artists Leon Trimble and Joel Cahen and gravitational waves researcher Dr Andrew Spencer from Glasgow University.

Two perspectives on the constellation of the Little Bear. Composer Stuart MacRae introduces a filmed performance of his quintet Ursa Minor, performed by the Hebrides Ensemble. Astronomer Dr Anne-Marie Weijmans of the University of St Andrews describes the constellation and tells the stories of some of its most remarkable stars.

This is a special event linking the frontiers of astrophysics with the frontiers of music – in the context of Orkney’s deep past. There will be new music and the story of its creation through the inspiration of gravitational waves, and something about their background as well. And there will be news of plans for a project for next year for which this is the first step.

Not so long ago the Clyde Valley was the fruit basket of Scotland. The Lanarkshire Songwriters have gathered memories from growers and pickers of those great days, and turned them into songs with schools and members of the community. Three of them, Billy Stewart, John Young and Wilf Yule, tell the story in words and music, with help from Andy Munro and local musicians.

Come and hear the Joyful Noise choir, made up of local folk including those living with dementia and their carers, in the shared enjoyment of music. Feel free to sing along with them in a wide range of songs, and stay afterwards for tea and home bakes and an opportunity to chat with members of the group and several visiting and local experts.

Nordic Viola and Faroese ensemble Aldubáran capture the strangeness, wonder and melancholy of Norse legends in a performance of music, film and specially commissioned art. Music by Faroese, Scottish and Irish composers is accompanied on screen by video by Craig Sinclair and abstract art painted by Orla Stevens, “an artist who works from a deeply embedded sense of place.”
