Gillian Keith performed with Sir John Eliot Gardiner throughout Europe and in the USA on his year 2000 Bach Cantata Pilgrimage, and in 2001 she sang as soloist with Gardiner in performances of Handel’s Messiah and Israel in Egypt in Germany, Austria and Turkey. She sang the role of Josabeth in Athalia in the 2001 London Handel Festival. Of her performance the Financial Times wrote, ‘Keith sang radiantly, with a fluent technique...and showed a wonderful polished quality high in her register.’ She has recently appeared at the Brighton Festival with Richard Hickox and the City of London Sinfonia, the Felicja Blumental Festival in Tel Aviv with Yuli Turovsky and I Musici de Montreal, and the Cheltenham Festival where she gave the world premiere of Clandestiny by the British composer Simon Holt. Gillian made her Wigmore Hall recital debut in June 2001. Recent engagements include a programme of concert arias by Mozart and his contemporaries with the Classical Opera Company, of which the Evening Standard wrote, &'145;...she sang with easy brilliance, thrilling in Mozart’s Per pieta with the silky tone of her top notes.’ Forthcoming engagements include a recital for CBS Radio in Montreal, a performance with the Los Angeles Bach Society and a recital in the 2002 Newbury Festival.

Gillian’s operatic roles have included Papagena The Magic Flute for Toronto’s Opera Atelier and Belinda in Purcell’s Dido and Aeneas with The Orchestra of the Age of Enlightenment. Recent engagements include soprano soloist in English National Opera’s staging of Bach’s St John Passion. Future plans include Woodbird Siegfried and Amor Orfeo for Scottish Opera. Gillian studies with Ian Partridge and Barbara Bonney.
