Kyriakos Sfetsas was born on September 29, 1945, in Amfilochia. He was raised in Lefkada where, at an early age, he studied music for the first time at the Philarmonic Band and the National Conservatory of the city with the late Fotis Vlachos. He continued his studies at the National Conservatory of Athens (1963-1966), where he studied the piano with Krino Kalomiri and theory of music with Michalis Vourtsis. On August 30, 1964, in Lefkada, he accompanied on the piano Maria Callas in her last performance in Greece. A few months after the 1967 dictatorship, he moved to Paris. There, on a French State scholarship (1969-1972), he pursued further studies with the composer and educator Max Deutsch (composition, analysis, orchestral conducting), while seeking the mentorship and advice of I. Xenakis, Luigi Nono and Henri Dutilleux.
The first public performance of his work (Episodes for piano solo) took place just after the uprising of May ’68 at the “Latin America Hall” in Paris, receiving favourable reviews.
He returned to Greece in Autumn 1975, this time to stay. At the invitation of Manos Hatzidakis, he worked at the Third Programme of the Hellenic Radio (1975-1976) as a free lance producer.
In 1977, as a regular employee of the Hellenic Radio, he served as head of the music departments of the 2nd and 1st Programmes, and from the summer of 1982 to January 1994 as director of the 3rd Programme.
Since 1999 he lives and works in Lefkada, the place where he grew up and made his first steps in music.
From 1999 until 2002 he was the Artistic Director of the Cultural Center of the Municipality of Lefkada and culturalinstitutions “Speech and Art Festival” “International Percussion Festival” and “International Folklore Festival.”
