"Adams, Plaid and Persen combined the poem with electronic music and the ambisonic field recordings to produce a piece titled Nord Rute -- the first in a four-part collection of performances about indiginous peoples titled The Compass Series, which merge poetry from Valkaeapää, music from Plaid and ambient audio from Adams. Nord Rute is a narrative account of the Sami people's annual migration.

The resulting performance is described as a "three dimensional psycho-acoustic experience" and an "ambisonic narrative evocation". During a performance the floor is covered with reindeer pelts and surrounded by speakers that create a plane of sound within which blindfolded audience members can immerse themselves in the atmosphere of the journey across the frozen wastes. To enhance the experience, there'll be absolutely no heating -- blankets will be provided and schnapps will be served instead."

"Teaching stroke patients to sing "rewires" their brains, helping them recover their speech, say scientists.

"Singing aloud leaves you with a sense of levity and contentedness. And then there are what I would call "civilizational benefits." When you sing with a group of people, you learn how to subsume yourself into a group consciousness because a capella singing is all about the immersion of the self into the community. That's one of the great feelings -- to stop being me for a little while and to become us. That way lies empathy, the great social virtue."
