What separates this narrative from conventional historical drama is its deep structural engagement with the history of sound. Lionel and David are not wandering aimlessly; they are ethnomusicologists on a mission to capture a dying rural oral tradition before industrialization and the mechanized horrors of modern war erase it forever. They record work songs, traditional sea shanties, and Appalachian hymns directly onto fragile wax cylinders.
The film's sound design team spent months sourcing original 1910s cylinder recordings to replicate the tactile hiss, warble, and compression of antique playback. The folk songs, performed in unadorned acoustic arrangements by Mescal, O'Connor, and local non-professional singers, anchor the film in historical truth. When David speaks into the horn of the phonograph, the mechanical reproduction captures something ephemeral: breath, presence, mortality. The tragedy lies in the mechanical limitation of the medium. The phonograph captures pitch, but it cannot capture the physical touch or the silent glances shared while the cylinder spun.
