A winner of five first prizes at the National Superior Conservatory of Music of Paris, where she studied with Yves Nat, Martine Joste is one of the most brilliant French pianists of today. After perfecting her skills in Sienna (Italy), Tanglewood (USA) and the Mozarteum of Salzburg (Austria), studying with Paul Badura-Skoda, she became accompanist and rehearsal pianist Irène Joachim's vocal classes at the Conservatoire of Paris, where she also taught sight-reading. A solo artist in residence at Radio-France, Martine Joste began an international concert career which has taken her to all the European countries, the USA, Brazil, Japan, Mexico, Uruguay, Canada and the Middle-East.

A passionate advocate of contemporary music, she performs regularly with numerous ensembles. As a soloist, she has given first performances of more than 40 works (by Jean-Claude Risset, Alain Bancquart, Bruce Mather, Claude Ballif, Ivan Wyschnegradsky, Fernand Vandenbogaerde, among others), several of which she requested and are dedicated to her. In 1992, John Cage composed one of his last works, Two6 for her and the violonist Ami Flammer. In 1995, Sylvano Bussotti composed and dedicated the Sonatina Gioacchina to her
