Carols from Trinity

Carols from Trinity is a 2-disc CD set of music by The Choir of Trinity College, Cambridge, directed by Richard Marlow.

from the notes included in the CD:

For well over a thousand years, the feast of Christmas has inspired composers from countless nationalities and Christian traditions. These recordings reflect the enormous diversity of the repertory which has resulted - a repertory which includes chant, medieval songs, carols, motets and modern church anthems.

I can't find any of this online to listen to, but you can buy it here at Amazon.com.
