Laurence Brisset initially studied harpsichord with William Christie and Noëlle Spieth at the Lille Conservatory (CNR) before devoting herself to singing. She was unanimously awarded a Premier Prix in voice at the Versailles Conservatory (CNR) and was admitted to the postgraduate course in opera at the Conservatoire National Supérieur of Paris, studying with Xavier Depraz. She simultaneously studied early musical notation and took part in many concerts and recordings with the Organum (1983-2000) and Discantus (1989-1992) ensembles.

Her deep interest in the Middle Ages was shared by several friends and led them to found the De Caelis ensemble in 1998 with Brisset as artistic director.
She is a qualified teacher of vocal technique and divides her time between concerts and voice teaching. She also acts as a tutor for the Royaumont Foundation under the aegis of the Programme for Research and Interpretation of Mediaeval Music (PRIMM). Since 2005 she has given regular master classes in the music and culture of the Middle Ages at the Conservatoire Supérieur de Musique of Geneva.

Having pursued a double training in music and in theatre, Florence Limon now pursues a career in both of these fields as performer, director and teacher. She first sang in the chorus of the Théâtre du Châtelet from 1980 to 1983 and went on to perform many roles in contemporary music theatre and operetta. She is a fully-qualified teacher of vocal technique and teaches voice and drama in several conservatories.
She is a founding member of De Caelis and takes an active part in all its activities. She also works regularly alongside Laurence Brisset as a tutor for the professional training courses organised by the Royaumont Foundation.

Awarded a Premier Prix in voice by the City of Paris as well as the Silver Medal of the Conservatoire National du région de Paris, Estelle Nadau appeared frequently as a soloist in oratorio at the same time as she completed her training in mediaeval music, studying at the Royaumont Foundation as well as at the Centre de Musique Médiévale in Paris.
She is also a member of the Diabolus in Musica ensemble (dir. Antoine Guerber), with whom she performs the songs of the troubadours and the trouvères as well as other works.
Estelle Nadau has been a member of De Caelis since 1999.

It was while taking part in the festival of d’Aix-en-Provence as a twenty year old dancer that Caroline Tarrit first became interested in singing. She began her studies in the early music department of the Toulouse Conservatory and then studied with Isabel Garcisanz (Paris XVIe) with whom she gained her Premier Prix in voice. She has worked both as a soloist and with the Musicatreize, Soli Tutti and Akademia ensembles in a varied repertoire that includes works by Bach, Mozart, Messiaen, Hersant, Escaich and Ohana. She has appeared as a soloist with La Fenice since 2004, performing Monteverdi’s Lettera amorosa and the role of Prosepina in L’Orfeo in particular.
One of the founding members of De Caelis, she takes a full part in all of the ensemble’s activities, both musical and interdisciplinary.

Initially having studied piano, Léna Orye then trained as a singer at the Conservatoire du Centre in Paris under Sonia Nigoghossian.
