Trained at the Maîtrise de Fourvière in Lyon, then at the Conservatoire Supérieur de Paris, Olivier Coiffet is appreciated for the quality of his interpretations of the Baroque and Romantic repertoires, as well as for his attention to declamation and drama.

After graduating from Sciences-Po Paris in 2004, he turned to music, performing as a soloist with some of Europe's finest ensembles: Ricercar Consort (Pierlot), Pygmalion (Pichon), Collegium Vocale (Herreweghe), Le Poème harmonique (Dumestre), Gli angeli Genève (MacLeod), Huelgas Ensemble (Van Nevel), La Fenice (Tubéry), Vox Luminis (Meunier), Correspondances (Daucé), I gemelli (Gonzalez Toro), Le Caravansérail (Cuiller), Doulce Mémoire (Raisin-Dadre)...

His committed interpretations of the Evangelists in Bach's Passions and Oratorios have earned him numerous invitations, notably in Poland, Great Britain, Switzerland, Germany and Luxembourg. He also devotes himself to Lied and mélodie, from Mozart to Berg, via Schumann, Fauré, Poulenc, Debussy...

On stage and on record, he performs in contemporary works such as Bruno Mantovani's L'Enterrement de Mozart, in which he plays the lead role, and Fernando Fiszbein's L'homme qui aimait... (at Buenos Aires' Teatro Colón). He is also in demand for baroque opera: with le Poème harmonique and Vincent Dumestre, he plays the title role in Pagliardi's Caligula delirante (numerous festivals in France and France Musique broadcast).

Recently, he has appeared as soloist at numerous festivals: with the Orchestre de chambre de Lausanne (works by Beethoven and Niels Gade), with the Pygmalion ensemble in Monteverdi's Vespers of the Virgin (Bordeaux, Pulsations), I Gemelli (Cozzolani's Vespers in Ambronay & Monteverdi's L'Orfeo in Pontoise and Tours), Musicatreize (work by Zad Moultaka, Venice), with La Fenice (Monteverdi - Vespers, Lausanne) and in numerous tribute concerts to Josquin Desprez with the Huelgas Ensemble and Ensemble Clément Janequin (conductor Dominique Visse). In 2023, he sang the Evangelist in Bach's Weihnachtsoratorium in Montreux and at Geneva Cathedral, and on numerous occasions in the Johannes-Passion and Matthäus-Passion, notably in Lyon, Vevey, Geneva and Berne, with the Arabesque Ensemble and the Freitagsakademie de Berne. In 2024, he will sing the Matthäus-Passion, again as evangelist, with the Ricercar consort, conducted by Philippe Pierlot, at the Fontevraud Easter Festival and at the Liège Opera.
