If you want to hear one of the most heavenly works to end this Christmas season (or wait until next winter), listen to Michael Praetorius' Christmas Mass.  I heard it for the first time a few years ago and it still blows me away at how beautiful it sounds.  Try the 1994 recording of the Gabrieli Consort & Gabrieli Players & Paul McCreesh.  http://spoti.fi/XtSXAL
