A selection of musical settings for the ancient Vesperal hymn «O Joyous Light,» sung during the entrance at Great Vespers. This collection includes a versatile arrangement by Monk Martin of Platina, suitable for both mixed (SAB) and male (TTB) ensembles, as well as an adaptation of the traditional Carpatho-Russian chant. These settings bring the serene and prayerful atmosphere of the lighting of the lamps to the English-speaking liturgy.
