I love a lot of the special music for this time of year, so I've tried to make do with listening to recordings and singing on my own. I found an absolute treasure-trove of downloadable free scores at the Choral Public Domain Library (CPDL) site - they have six pages worth of Music for the Advent, Christmas and Epiphany seasons, including traditional carols as well as choral music from the 14th century to the present.
One new discovery is Charpentier's 'Salve puerule':
And this is a lovely concert/documentary hybrid - a special Christmas episode of the BBC series Sacred Music (featuring The Sixteen), 'A Choral Christmas':
I recognised several pieces I've sung over the years, including Victoria's amazing 'O Magnum Mysterium', and the 15thC carol 'There is no Rose of such Virtue'.
Merry Christmas, folks! Enjoy your holiday. :)
