This series by John Gallaher and Rusty Morrison is a true call and response. Morrison's calls become Gallaher's responses become Morrison's calls again. This series is not a simple dialogue; rather, the calls and responses function as voices in a harmony variously euphonious and cacophonous. So it is only appropriate that the series begins with "Inside the talking room": inside this echoing environment, one voice–"Staying as a Form of Departure"–becomes the response "If You Hadn't Stayed the Departure, I Wouldn't Have Formed." Each call and response marks an incremental change, a mutation, which carries the conversational melody in surprising directions.
