With this recording New York City's Voices of Ascension and Conductor Keene celebrate the 900th birthday of one of the most remarkable creative spirits of the Middle Ages, the Abbess Hildegard of Bingen (1098-1179). Although some musicians embellish Hildegard's single line chants with additional parts, the Voices of Ascension's approach is to present the inspired poetry and music of this mystic visionary 'pure,' without any contemporary additions. We are hearing, in these 14 haunting pieces, the Women of the Voices of Ascension, a mixed-voice choir on all their other excellent recordings. Soloists Kathy Theil, Michele Eaton, Alexandra Montano and Allessandra Visconti are particularly wonderful on cuts like 'O virga ac diadema,' 'Vos Flores Rosarum,' 'Et Ideo,' 'O Pastor animarum,''Caritas Abundat,' 'Ave, generosa' and 'O Jerusalem, aurea civitatus.' All beautiful, soaring a cappella. This is simple, powerful music that touches and speaks to us across more than 8 centuries, in a way that its composer could never have imagined.
