Tigris
This article describes a durational walking installation (2023–ongoing). For the companion downriver work, see Euphrates. For other water-boundary pieces, see The Brahmaputra Frequency Walk and Immersive works and Beach Surgery.
A durational walking pilgrimage following the Tigris River's edge through Baghdad, structured around the sound of the earth rubbing against space and the Kármán line — the boundary where atmosphere becomes void. Participants walk the river while listening to layered recordings: water-sounds, frequency sweeps, archival voices, and embedded quotations from Beach Surgery as whispers beneath the audible.
The work treats the Tigris as an ontologically incomplete space: a river flowing in one direction yet whose resonance circles backward, a boundary that exists but cannot be fixed. Walking it mirrors traversing the rural/desert interior — crossing a landscape one cannot hold in mind at once.
The Seven Stations
At seven listening posts along the river, participants attune to frequencies associated with the spine's resonance and Kármán transgression. These frequencies manifest only through binaural reception; the work refuses documentation or representation. You must walk and listen to know it. Return visits are built into the archive's design; few complete all stations in a single visit. The incomplete walk is the point.
