The lyrics of "A Sudden Swing" seem to be describing the experience of approaching death. The singer says that she has walked her body to the "rim of its end," and describes a sudden swing or shift in her body - perhaps a physical sensation or a metaphor for the suddenness of death. The imagery of "a skin of wing" is striking and suggests a transformation or release, as if the singer is shedding her bodily confines and taking flight. The repetition of "along my spine" may suggest a focus on the physical body and its limitations and potentials. Overall, the song seems to be an exploration of mortality and the boundaries of the self. The haunting, atmospheric soundscapes created by Jenny Hval and Susanna enhance the otherworldly, mystical quality of the lyrics.
