Eya follows the humming routes of the camino de Santiago, and the path towards the rocky mountaintop monastery of Montserrat with music of medieval Spain drawn from the Codex Calixtinus, Las Huelgas Codex, and the Llibre Vermell. Interspersed throughout the program are the love songs of Hildegard von Bingen devoted to St. Ursula and the 11,000 virgins, martyred along their spiritual pilgrimage.
