The sound piece is based around geophonic recordings of Kate’s bicycle, capturing its vibrations as it moves. The trips morph into examinations of specific metallic structures: a communication tower in the jungle of southern Mexico resonating in response to birds landing on it, pipes from a raised highway bridge in Saskatoon Canada, reverberating the journeys of commuters above and a simple fence wire groaning with tension as the wind forces it against a gorse bush in Scotland.
