"Vision--The Music of Hildegard von Bingen"? Make that "Hildegard--the Dance Remix." (Yes, it has been used on the dance floor of at least one New York City nightclub.) What else can you call it when Richard Souther takes the stark, ecstatic plainchant of the 12th-century abbess and adds heavily produced electronic trance-and-dance tracks? Souther's additions aren't bad in themselves--they are a bit New Age-y, yet danceable in a druggy 3:00-a.m. kind of way--but slather them over Hildegard's spare, intense chant melodies and the effect is perverse, if not just silly. Don't blame poor Emily van Evera--she is a fine interpreter of Hildegard, and EMI simply asked her to record some unaccompanied solo tracks of the abbess's music and send in the tapes; she had no idea what was going to be done with them until this disc came out with her name on it. This shows up in the final product: the gently fluid pulse van Evera applied to Hildegard's music (which would make perfect sense in the a cappella performance she thought she was giving) feels completely disconnected from the rigid rhythms inherent in Souther's electronic accompaniment. Now, there are a number of customer reviews, below, from listeners who like this title a great deal--have a look at them, check out the sound clips, and by all means get this title if you're interested. But, if you're curious about Hildegard, go to the recording that made her famous eight centuries after her death: A Feather on the Breath of God. --Matthew Westphal
