Her interest in the avant-garde resulted in her creating her own very personal vision of scenic art, video and minimalist music. Her investigation is centred on the the human voice, voice techniques, tonality and register. Her interest in the avant-garde also includes video, minimal music, stage arts and artist-public interaction.
