Sound artist Viv Corringham invites local people in communities around the world to take her on “Shadow Walks” through their neighborhood. She records the conversations. Later she retraces the person’s walk on her own and “sings the walk” through vocal improvisations, and records her singing. These recordings are edited together to make the final sound piece. “Broken Land” from her CD “Walking” is the result of my taking her on a walk along the Gowanus Canal.
