Ian Wilson’s ‘Una Santa Oscura’ (’an obscure saint’) is inspired by Hildegard of Bingen, a German abbess, mystic and composer. The music is partly ritualistic and meditative in nature, structured to reflect a ‘cloistered’ day. An electronically-generated tape part plays almost continuously, and much of its basis is one of Hildegard’s compositions, ‘Ave Maria, O auctrix vite’, which is heard at the very end of the work. The work is performed by Ioana Petcu-Colan.
