After receiving diplomas in piano performance and composition from the Schola Cantorum de Paris, Astrinidis embarked on an international career as pianist (soloist or accompanist).
During the 1950s and the early 1960s, he toured East Asia and the Americas, performing in cities, such as Evanston[2] and Hong Kong.
[3] He collaborated with renowned performers of the period, such as violinists Jacques Thibaud, Henryk Szeryng,[4] Colette Frantz,[5] and cellist Bernard Michelin.
[10] His other symphonic music includes the oratorios The Youth of Alexander the Great, Cyril and Methodius (1966), the choral Symphony "1821" (1971), the Cypriot Rhapsody, three concertos: Variations Concertantes for piano and orchestra (1952–55), Concerto-Rhapsody for violin and orchestra (1979), and Concerto pour Guitare et Orchestre (2007).
[12] In December 2020, pianist Stephanos Katsaros[13] launched a 12-part mini-documentaries with live performances of Astrinidis' piano and chamber music works.
