Keller’s repertoire as a soprano extends from early music to premiers of contemporary works that underline the complementarity of written and improvised music. She earned a master’s degree in Visual Arts while simultaneously studying voice, jazz, and contemporary vocal repertoire at the Music Academy of Strasbourg. She also pursued complementary studies in contemporary dance and theatre. She has sung for many composers, including François Rossé, Gualtiero Dazzi, Jean-Pierre Drouet, Christophe Havel, Hans Joachim Hespos, Thierry Alla, and José Luis Campana. She has performed works by Giacinto Scelsi, Georges Aperghis, John Cage, Luca Francesconi, and Gyorgy Kurtag. She has collaborated with dance, musical theatre and théâtre d’objet companies, including Cie Adèle Riton (Strasburg), Cie Blu (Italy), Cie Le Grain (Bordeaux), Cie Malene Hertz (Denmark), Cie Archipel Indigo (Strasburg), Cie Médiane (Strasburg), and La Cie Toujours après minuit — Brigitte Seth and Roser Montlló Guberna (Paris), with whom she has premiered many works in France and elsewhere in Europe.
