I heard this song on NPR this afternoon and HAD to track it down. Choir Of Young Believers are a Danish band, based out of Copenhagen, and this track can be found on the record 'This Is For The White In Your Eyes' which I believe goes on sale in August here in the states. I say band, but the project is basically a vehicle for singer/songwriter Jannis Noya Makrigiannis.
Beautiful, haunting stuff...give a listen.
