It Must Have Been Dark By Then

It Must Have Been Dark By Then' is a book and audio experience that uses a mixture of evocative music, narration and field recording to bring you stories of changing environments, from the swamplands of Louisiana, to empty Latvian villages and the edge of the Tunisian Sahara. Unlike many audio guides, there is no preset route, the software builds a unique map for each person’s experience. It is up to you to choose your own path through the city, connecting the remote to the immediate, the precious to the disappearing.
