Deborah Kayser performs in areas as diverse as ancient Byzantine chant, French and German Baroque song and classical contemporary music, both scored and improvised. Her work has led her to tour regularly both within Australia, and internationally to Europe and Asia. She has recorded, as soloist, on numerous CDs, and her work is frequently broadcast on ABC FM. As a member of Jouissance, and the contemporary music ensembles Elision and Libra, she has performed radical interpretations of Byzantine and Medieval chant, and given premières of works written specifically for her voice by many composers. Her performance highlights include works by composers Liza Lim, Richard Barrett and Chris Dench, her collaboration with bassist Nick Tsiavos, and oratorio and choral works with Douglas Lawrence. She was a member of the Choir of Ormond College for eight years from 1984, and has been the Principal Soprano of the Scot’s church since 1991.
