Youtube is fun for this kind of thing...
Malankara (Syriac) Orthodox hymn from Vespers on the Feast of the Nativity (in Malayalam)
Three Coptic Orthodox hymns sung on Christmas Eve (forgive the rough sound here; it's one of the only clips that isn't from the annual liturgy at the cathedral in Cairo, which are generally converted really poorly with lots of glitches, missing parts, etc.) This includes my personal favorite, "Eparthenos", which you can hear in a different version with instruments courtesy of Ensemble David, with a long introductory explanation of the meaning and approach to the hymn, in
this video)
One of my favorite EOTC nativity hymns,
"The Savior of the world is born today"Mar Sewerios Malki Mourad singing
Christmas prayers in Syriac From the Byzantines,
"Miladouka" is one of my favorites, but not this version (just couldn't find my favorite, from the departed Metropolitan of Tripoli, Lebanon, Elias Qurban), so enjoy
this hymn, and
this one.
I'm having a hard time finding individual Christmas hymns from the Armenian tradition (probably because I don't really know much about it, and don't speak the language), but I thought
this video was very beautiful and well done. I'm sure any of the board's Armenians can find tons of wonderful things for this thread.
