While she has often integrated photographic materials and processes into her painting, her primary concern has always been an exploration of painting itself as a medium. Her most recent body of work is a typically idiosyncratic investigation of the traditions of landscape painting, via a witty parody of the landscapes of the Romantic period. Susan Philipsz' work deals with the spatial properties of sound and with the relationships between sound and architecture. She is interested primarily in the emotive and psychological properties of sound, and how it can be used as a device to alter individual consciousness. She has used sound, and more recently song, as a medium in public spaces to interject through the ambient noises of the everyday in public spaces.
