Orkney has a great heritage of music so for this weeks Open Country Helen Mark visits the St Magnus International Festival of Music and Arts. Now in its 40th year St Magnus was founded by the late Orkney-based composer, and Master of the Queen's Music, Sir Peter Maxwell Davies. This years festival will celebrate his legacy as well as shining a light on new talent from the islands.

During the summer months Orkney enjoys 'Twilight All Night' due to its latitude, Helen discovers what this means for the people who live there and the festival. She meets local musicians and composers to find out how the unique landscape, history and wildlife of Orkney inspire individual creativity and how music contributes to the community spirit so integral to island life.
