After graduating from the Paris Conservatoire and obtaining her Concert Diploma from the École normale de musique in Paris by unanimous vote, Lydia Jardon was recognized by the Cziffra Foundation and won the Milosz Magin International Competition. She then chose to launch a concert career. In July 2001 she was chosen for the opening concert at the Newport Festival in the United States. After playing in France, Germany, Austria, Uruguay, Brazil, Turkey, Colombia, and many Eastern European countries, she interpreted Beethoven's Fifth Concerto in Japan at Suntory Hall with the Tokyo Symphony Orchestra under the direction of Yuri Nakamura, Rachmaninov's Third Concerto in Bratislava with the Slovak Radio Orchestra conducted by Jean-Paul Penin, and Rhapsody in Blue at Geneva's Victoria Hall with the Orchestre de la Suisse Romande conducted by Arthur Fagen. At the end of 2001, she founded the first record company for women: Ar Ré-Sé (meaning "those women there" in Breton), an independent organization with which she unearths forgotten scores by great masters who are part of the universal heritage--Koechlin, Medtner, Lekeu, Magnard--making it a point of honor to entrust them to excellent women performers who are often just setting out on their careers.
