Oh, I wish I was at this concert! Maja Ratkje´s "Crepuscular Hour" was performed in Uranienborg church in Oslo during the Ultima 2010 festival . They used three choirs, six noise musicians (Stian Westerhus included) and church organ! You might be able to take a listen on the Norwegian radio NRK P2, 29 September at 21:00.
I heard Sunn o))) in a church in Bergen during Borealis 2007, and hope someone will get the same idea about this work! Come on, anybody!?
