Crepuscular Hour is an epic, hypnotic one-hour piece for three choirs, three pairs of noise musicians, and church organ, to be performed in a cathedral or similar location with musicians surrounding the audience. The room fills with sound in an intense, but almost meditative hour, as the voices blend with the distortion, the noise sometimes takes over, and the organ eventually takes the music to a new level. The visual design of this concert is a play on the crepuscular rays -- rays of sunlight that appear to radiate through clouds from the point in the sky where the sun is located -- with the light filtered by the obstacles and musicians in the room. All texts are from the Nag Hammadi library, a collection of Gnostic texts discovered in Upper Egypt in 1945. These texts have provided a major re-evaluation of early Christian history. This recording of a performance of the piece includes a DVD of the whole concert, beautifully directed by Kathy Hinde (DVD is PAL format, region-free, with 5.1 and stereo audio).

She has made large gallery works with SPUNK and made music for a radio play by Elfriede Jelinek, and in 2003, she played a part in her own opera, also based on texts from the Nag Hammadi library.
