Fabienne has performed in numerous oratorios throughout Europe. In 1992 she sang the Soprano solo in Brahms' German Requiem with the Orchestre de la Garde Républicaine of Paris under the direction of Roger Boutry. This led to numerous appointments with various choirs and orchestras in Angers.
She toured in Europe and Canada with the Choir and Orchestra of Vox Campus singing Vivaldi's Gloria, Handel's Messiah, Poulenc's Gloria, Mozart's Requiem and the Te Deum by Charpentier.
Other oratorios include Bach's B minor Mass and Magnificat, Mozart's Coronation Mass, Fauré's Requiem, Haydn's Paukenmesse and the Mass in D by Dvorak.
After moving to the UK, she performed Verdi's Requiem with the Bristol Symphonic Orchestra. She has also worked with Michael Nebe and the Fine Arts Sinfonia of London at St Martin-in-the-Fields, singing a variety of oratorios, most recently the Stabat Mater by Pergolesi in 2006.
