Vis.[un]necessary force_4 (V.[u]nf_4) is a participatory sound installation developed from field recordings made during a full day with Las Rastreadoras de El Fuerte near Los Mochis, Sinaloa, in February 2019. The work remains silent until a visitor activates one of three sections through a touchscreen. An eight-channel loudspeaker ring places speech, wind, footsteps, tools and terrain at ear height.
