The language is Greek. The hymn's are "Axion Estin" and "Kyrie Eleison". The artist is Divna, and if you have itunes, you can purchase her CD through it.
If you want the lyrics they are :
It is truly meet to bless thee, O Theotokos,
ever blessed, and most pure, and the Mother of our God.
More honorable than the cherubim,
and beyond compare more glorious than the seraphim.
Without corruption thou gavest birth to God the Word.
True Theotokos, we magnify thee.
Khristos anesti ek nekron,
Thanato thanaton patisas,
Kai tis en tis mnimasi
Christ is risen from the dead,
Trampling down death by death,
And upon those in the tombs
