Ah ok. Since you liked this one, i MUST suggest the version from the Simonos Petras (Simon's Stone) monks, which has very original sounding and the one from orthodox christians in the kingdom of Bahrein which is superb (half greek chanting, half their language). Also if you don't know, this particular hymn has been written by saint Nectarios of Aegina himself. I suggest also to read the lyrics (from some translation of course). Here are the videos
