She has appeared in masterclasses with Jessica Cash, Diane Forlano, Barbara Pearson and Esther Salaman. "An exquisite soprano" wrote the Musical Times, after a recital that had been "lifted into ecstasy."

She has performed throughout Europe, India, Japan and the U.S.A. Engagements include a tour of South Africa singing Mahler's Resurrection Symphony and Das Knaben Wunderhorn; recording the title role in Handel's Deborah for German radio; concerts at the Mathieson Music School, Calcutta 2nd International Festival; the Tel Aviv Festival for Vocal Music; the Zaarlouis Festival; and premieres of Gritton, Warton-Steward and Wishart; as well as numerous appearances in London and the provinces.

Ghislaine is as equally at home with early music as more contemporary genres, having sung for 10 years with such groups as the Tallis Scholars, The Sixteen and the Monteverdi Choir before pursuing her own individual career. According to demand she has appeared as a washing machine, tongue trilled in a Calcutta garden, and sung Mozart from under a table cloth. Ghislaine can be heard regularly on Classic FM, and also on the EMI, Gimell, Naxos, Richmond and Regent labels, Mozart's Laudate Dominum being singled out by Gramophone.

Ghislaine is widely sought after as a coach of individuals and choirs. Her driving passion is encouraging others to be expressive with confidence and to this end Educational Kinesiology and Estill Voicecraft are employed. She is adviser to the Finchley Children's Music Group and the Mathieson Music School, Calcutta, and director of workshops in Britain, Holland and Spain.
