In 2012, at just 21 years old, he became one of the youngest performers ever to take First Prize at the International Harpsichord Competition in Bruges (MAfestival 2012), also winning the EUBO Development Trust prize; an accolade bestowed on the most promising young musician of the European Union. The same year, he claimed second place in the Prague Spring International Harpsichord Competition (64th edition of the Festival, 2012), along with a nod for the best interpretation of the contemporary piece composed specially for that contest. In 2013, he also won the Prix des Radios Francophones Publiques.
Rondeau is in demand for solo, chamber music and orchestral appearances throughout Europe and in the United States. He frequently performs with the Baroque quartet Nevermind. Quite apart from his activities as harpsichordist, he founded the ensemble Note Forget, presenting his own jazz-oriented compositions and improvisations on piano.
Rondeau is signed to Erato as an exclusive recording artist. January 2015 saw the release of his debut solo album, Imagine, dedicated to the music of J. S. Bach on the harpsichord. In February 2015, he was named "Revelation soliste instrumental" at the prestigious Victoires de la musique classique.
