In her florid music, the 12^th-cen­tu­ry mys­tic Hildegard von Bingen rais­es the Gregorian tra­di­tion to unprece­dent­ed heights. The Tiburtina Ensemble com­bines her com­po­si­tions with ear­ly poly­phon­ic music from the School of Notre Dame. A por­trait of a strong woman in a tur­bu­lent man’s world: an inspired sibyl .nd a human of flesh and blood.
