This is a record made in Grain Tower Battery, off the Isle of Hoo. It cam e out of a research period looking at layers of history and space/infrastructure, old english fate weaving and herbal learning, and stone tape theory. This has also spawned the bootlegspatialrecall.net site, please visit. More info on the dedicated page for the project. I made this work as part of the New Voices program 2019-2020 supported by Sound and Music
