They first shared the stage in 2019 as concertmaster and principal cello in parisian-based chamber ensembles, posts they subsequently held for five years before embarking on the creation of a collaborative chamber music project and appearing since as duo concerto soloists.

United by their dedication to chamber music, they launched Arborescences Sonores as a concert series in 2024, bringing together international colleagues around bold and imaginative chamber repertoire. 

Their concerts feature a vast array of repertoire: duos by Kodaly, Honegger, Bartok, Xenakis, string trios of Beethoven, Jean Cras, and Gideon Klein ; the clarinet trios of Bartok, Paul Schoenfeld, Orlando Bass; Messiaen’s Quartet for the End of Time, string quintets of Brahms and Schubert, string sextets of Tchaikovsky, Schoenberg and Brahms, works for mixed chamber groups involving harp, clarinet and flute by Ravel, Jolivet, Ursula Mamlok, and André Caplet, among others.

Enthusiastic about opening new doors and nourishing fresh dialogues between the arts, Rachel and Florimond often curate musical programs with the aim to present them in architecturally unique or historically-charged spaces, as well as programs tailored for the visual arts.

Their respective careers encompass international solo and chamber music appearances, as well as vast previous orchestral experience as guest soloists. In 2023 they created the Arborescences Trio with pianist François Daudet.
