What kind of music has Orthodoxy brought us? In addition to the church hymns of Bortnyansky, Grechaninov and Znamenny chant. I thought that there is one style that is essentially Orthodox - reggae. Indeed, Rastafarianism is an Orthodox apocalyptic sect. Yes, this sect is heretical, marginal. But there is no question of dogma in music; style and vibe are more important here. And the vibe and style of the Rastas is Orthodox.
Rastafarianism is influenced by the Ethiopian Orthodox Church, they value the heritage of the Old Testament, as Orthodox, priests of the Nyabinghi order wear Orthodox priestly robes. Their teaching speaks not only about personal salvation from hell, but about salvation as the liberation not only of oneself, but of all creation.
Also a clear understanding of the world lying in evil - Babylon and the Divine reality - Zion. They intuitively understood the divine energies, although they only recognized them in the "root vibration" expressed in music. Of course, as in any sect, they have a lot of limitations and mistakes. But the more valuable are their spiritual achievements. I've never thought of reggae as anything other than a purely religious, worshipful thing. In general, cult music in every sense.
