Here is an outstanding resource for Orthodox Liturgical Music, created by an American monastic.
When I was on pilgrimage at Archangel Michael Monastery in Canones NM in Autumn 2014, I recall being surprised by the compunctionate and familiar tones of some of the chants the brothers sang during Matins. Came to find out that one of them had been at St John of Shanghai & San Francisco Monastery in Manton CA, and brought with him a familiarity with the music on their beautiful CD, The Eyes of All Look to Thee with Hope.
So, when I recently happened across Monk Martin’s website, Orthodox Music, which includes sheet music for the hymns on the CD, plus much, much more, I was doubly intrigued. Not only do I long to return to Archangel Michael Monastery in New Mexico, but now I am even more desirous of making my first pilgrimage to All-Merciful Saviour Monastery on Vashon Island, from where Monk Martin hails.
