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 radio.
As a member of JOUISSANCE, and the contemporary music ensembles ELISION and LIBRA, she has performed radical interpretations of Byzantine and Medieval chant, and premiered works written specifically for her voice by local and overseas composers.
For Kayser, performance highlights include works by composers Liza Lim, Richard Barrett, David Young, Volker Heyne, Michael Finnissy, Helen Gifford and Chris Dench.
