Maja Solveig Kjelstrup Ratkje (1973) is quite a remarkable musician, singer, improviser and composer and Crepuscular Hour is quite an extraordinary piece of music, written as it is for the unusual line-up of three choirs, three pairs of noise musicians and church organ.

It's a one hour piece to be performed in a cathedral or similar with musicians surrounding the audience. The room will be filled with sound in an intense and dramatic, but also hypnotic and meditative hour, where the voices blend with the distortion, the noise sometimes taking over, and the organ eventually hoisting the music to a new dramaturgic level.

The piece is inspired by the phenomena crepuscular rays', which is when rays of sunlight stream from one point through gaps in clouds or other obstacles. The visual design of this concert is a play on the phenomena, with the light being filtered by the obstacles and musicians in the room.

All texts are from the Nag Hammadi Library, a collection of thirteen ancient books with over 50 texts that were discovered in upper Egypt in 1945. These texts have provided a major re-evaluation of early Christian history.

Crepuscular Hour was premiered at the Ultima Festival in Oslo in 2010, and the next realisation of the piece was at the Huddersfield Contemporary Music Festival in 2012, where this recording was done.

The concert was beautifully filmed and directed by Kathy Hinde and can be found on the DVD that comes with the CD.
