During Ionian Village 2010, the Quad Pod, composed of Jonathan Limberakis, Tommy Margaritis, Niko Lendaris and Mario Colosimo, chants "Agni Parthene" at Ossias Loukas.
so far to say Every Orthodox Church have people who sing as good as them. :) Only voice and the pure heart who is reaching Heaven when singing! When Singing this kind of songs with your soul you feel like you're not anymore on Earth and that you are in heaven singing in front of Mary mother of God... trust me I usually cry at the end when I do it will all my heart. Peace and prosperity and hope you'll gonna come back to the fold!
