Obsessive journal entries, clinical reports, varied sources of music, and a series of watercolors depicting a pierced and bleeding brain are among the many elements that make up a narrative around the occasion of mental breakdown. Instruments of electrical transmission are metaphors for the diseased brain, as reconstructed by a woman who has lost her reason, her body, and her foothold in personal identity. The unseen protagonist at first attributes her illness to repeated hearings of a Chopin mazurka on the radio.
