This film profiles three musicians who, while pursuing acclaimed solo careers, sometimes come together to form a distinctive trio: Gérard Barreaux, an accordionist who keeps the café concert tradition alive through his music. Ami Flammer, a violinist, soloist and professor at the Paris Conservatory; and Frédéric Stochl, principal double bassist of the Ensemble Intercontemporain and professor at the Paris Conservatory. This nameless, and almost non-existent trio, meets sporadically for occasional concerts, with no concern for any career ambitions. They have no real set repertoire either. Beethoven and swing waltzes, Berio and La Cumparsita, Gypsy and Yiddish melodies, Nino Rota and Schubert flow mixing sounds of the double bass, violin, and accordion. The audience is at the heart of this music, not divided by genres or styles, it is a single entity of art where the pitch of a Piaf song is the same as that of a Beethoven concert.
