Coming from diverse musical backgrounds, the 4 beautiful young women of Boston-based Tapestry came together to create new interpretations of mediaeval chant and polyphony, and to collaborate with contemporary composers in the creation of new works. 14 pieces, over half of them lovely, soaring chants by composer Hildegard von Bingen (1098-1179), like 'O lucidissima,' 'O cruor sanguinis,' 'O tu illustrata,' and 'O viridissima virga.' Interspersed are sacred works from the 13th century, like 'Novi sideris Lumen respenduit,' 'Deus misertus hominis' and 'Flos ut Rosa floruit.'
