Rainer Maria Rilke once imagined a phonograph needle tracing the sutures of a human skull to hear what it might contain. Brittany Miller's paintings move through a similar compulsion—toward caves, labyrinths, forests, and fortresses, spaces long associated with ritual and retreat. Primal Sound, her New York debut at Ruttkowski;68, presents meditative stacked lines that cohere up close and flicker at a distance, pressing toward encounters where the known and the incomprehensible meet.
