Another flawless Sequentia contibution to the complete works of Hildegard, this set uses the 10 minute title piece, written for the dedication of a church, to lay the cornerstone for a series of liturgical songs which might have been appropriate to such an occasion. As the church bells ring to set the stage for the recorded fantasia, the lovely choir begins and carries straight through a roller coaster of gems, occasionally colored by a spare but powerful addition of period instruments throughout, fiddle, harp, organ, flute. Characteristic Hildegard themes of the miraculous, holy virginity and its fruits amplify and adorn songs regarding the new church's patron Saint Rupert and his virtues, a duke's son and ascetic who died at 20. Sequentia's combination of vibrant performance and informed but creative reconstruction perfectly matches the spirit of the bold medieval composer and abbess Hildegard, as she in turn linked her own charisms to Rupert. The total effect is like a rare telescope look into a distant spiritual terrain, and quite absorbing.
