Ad lux tenebrae (also known as K Svetu T'my) first full-length album. Ad lux tenebrae - well-known masters of deep ritualistic Dark ambient from north of Riphean Mountains. Great powerful sounds from Primeval Ural Woods. To create music they use original musical instruments – bubens, handmade drums, blowing horns, flutes and others instruments made by musicians theyself and have no name. Disk contains two live recorded Rituals, each of them was played in this form only once and never will be repeated. First Ritual is fast, intense, rhythmical and disquiet. Second is appeased tranquil quiet. "Call of the wild" - this is about one hour of archaic and ritualistic music in total.
