Sigh was made in collaboration with the BBC Concert Orchestra and features a score made especially for it by Academy-Award winning composer Anne Dudley. Dudley comments, 'When I was composing this piece I had in mind Sam's wonderful large photographs from her series Wuthering Heights. This gave me the sense of loss that would transform onto the members of the orchestra as they played without their instruments. I knew that the sound of each section had to come from the right screen and this allowed me to think about the music travelling around the room. Also, I wanted the listener to be able to move around the room and experience a different perspective of sound – very much like strolling through an orchestra. All the sections rely on each other to complete the soundscape and avoid a greater loss.'
