Aviformes; Kamana; Parcours pour Santur; Paroles sur Lèvres; Paroles sur Langue; Lumière sans Ombre. Barbara Zanichelli, soprano; Anna Maria Kieffer, mezzo-soprano; Nicholas Isherwood, bass. Leo Kupper was born in Belgium in 1935. He worked with Henri Pousseur at the first electronic music studio in Belgium and is founder and director of the Studio de Recherches et de Structurations Electroniques Auditives in Brussels. This is his 3rd release on Pogus and he remains a master at working with electronics and the human voice. Of the six works presented on this CD, five involve the human voice. Sung by Barbara Zanichelli, Anna Maria Kieffer, and Nicholas Isherwood, their microphone recordings were integrated into Kupper's digital computer sessions - hence the title Digital Voices. The remaining work is for the santur. All the songs on this recording are abstract, which allows both composer and singer a certain artistic liberty. Kupper's stated goal in this recording of digital songs is to encourage the internationalization of spirituality through a musical language that accepts both sung and instrumental world sonorities that can be mixed with electronic sounds derived from the voices of the singers.
