He is regularly invited to play with all major Greek orchestras, as well as the national orchestras of Belgrade, Odessa, Cyprus, the Netherlands Chamber Orchestra and the Cairo Opera House Orchestra.

He has played in international festivals, such as the Printemps des arts de Monaco, New Masters on tour series in Amsterdam, Piano à Auxerres, the Hellenic Festival, Les Dominicains de Haute Alsace, the Dimitria Festival in Salonica, the Georges Bizet Festival in Bougival, Santander Music Encounters etc. Among his favourite chamber music partners are the Arditti Quartet and Patrice Fontanarosa.

His taste for experimental projects and his curiosity for different forms of artistic expression have brought him to contribute musically to Heinrich von Kleist’s La Marquise d’Ô, directed by Lukas Hemleb and produced by the Théâtre Gérard Philippe and the Maison de la Culture d’Amiens, or to create with Tal Isaac Hadad the performance «Le piano et le salon de musique», in the FIAC of October 2011. In February 2010, he also participated in the adaptation by Hervé Lacombe of the Arlesienne into a theatrical tale in the Musée d’Orsay.

He has recorded works of Alexander Scriabin for the Mécénat Musical de la Société Générale, and works of Manos Hadjidakis for the Italian foundation CIMA. His last CD, recorded in 2011 thanks to the Meyer Foundation, includes the whole oeuvre of Iannis Xenakis for solo piano, as well as Synaphaï, Xenakis’ legendary first piano concerto. The live recording An evening in Leipzig has just been released in the collection Mediencampus.

Stéphanos Thomopoulos is the first pianist in France to carry out a Doctorate in performance at the Conservatoire de Paris, where he does research on Xenakis’ piano work under the supervision of Gerard Pesson and Jean-Yves Bosseur. The writing of this thesis has brought him to participate in concerts and conferences about Xenakis in New York, Montreal, Paris, London, Belgrade, Leipzig, Athens, Monaco as well as to publish an article in the book Performing Xenakis, next to personalities such as Milan Kundera, Michel Tabachnik and Irvine Arditti (Pendragon Press).

In 2010, Stéphanos Thomopoulos was appointed professor and head of the piano departement at the Conservatoire National de Nice. He is invited to give masterclasses in Monaco, Musicalta in France and Music Village in Greece..
