I recently scored Charlie Crane's Child Soldier. A short film based on the true story of one boy's experience in the Angolan civil war. It's beautifully shot, and a moving and important subject. Both the director and I were keen for the music to support, rather than dominate the film and we spent a while experimenting with different colours. We settled on the sound of the viola to carry the voice of the film which John Garner performed very sensitively.
