To go rather off-topic, I've been truly impressed with the artistry, and amazingly wide range that Voces8 performs.
A quick search of you-tube pulled up a number of things worth listening to.
As an oboe-player myself I had to start with this one (a bach chorale more commonly known as "Jesu, joy of man's desiring")
But also a piece by a contemporary american choral composer Eric Whitacre, "sleep".
(I've performed this one twice as an arragement for concert band - two points of interest: first, it was intended to be a setting of a Robert Frost poem, but Frost's estate wouldn't give permission. So Whitacre persuaded a poet friend of his to write a new poem with the same meter and stresses, so that it would fit his music. The other thing that might make one smile is that Whitacre's first large scale work was a degree project at UNLV for concert band called "Godzilla eats Las Vegas". The music here though is utterly different.)
Going in the other direction, they have a transcription of an orchestra work, Nimrod for Elgar's "Enigma Variations":
and some movie music (from the Lord of the Rings):
