'11,000 Virgins - Chants for the Feast of St. Ursula' performed by the vocal quartet, Anonymous 4' is 72 minutes of music at least as good as any of their other albums. But, over half of the pieces on this record are by medieval composers OTHER than Fraulein Hildegard. So, the emphasis of the album is much more on 'Chants for the Feast of St. Ursula' than on Hildegard.
