Discover the world's earliest music by a female composer: 9th-century nun, poet, and hymnographer Kassian (Kassa). The same men and women of Cappella Romana who brought you the "Lost Voices of Hagia Sophia" bestseller (43 weeks on Billboard), now sing the earliest music we have by a female composer, including long-suppressed hymns recorded here for the first time. They close with two medieval versions of her beloved hymn for Orthodox Holy Week. Cappella Romana is the world's leading ensemble in the field of medieval Byzantine chant. Building on it's extensive catalogue of this repertoire, Hymns of Kassian is it's 25th release. This is the first of a planned series to record all of Kassian's surviving works.
