Born in Ioannina, Greece, he studied at the Greek Conservatory in Athens, the Juilliard School, Indiana University, and Michigan State University.
He spent much of his career in Louisiana. In 1967, he took up a post teaching composition at Louisiana State University, later serving as a Boyd professor of composition and director of the university's New Music Festival.
Additionally, he founded and conducted the Louisiana Sinfonietta and served as concertmaster of the Baton Rouge Symphony Orchestra.
His over 230 compositions have won numerous awards — including first prizes at the 1981 Brooklyn College International Chamber Competition, 1985 American New Music Consortium Distinguished Service Award, and numerous ASCAP Standard Awards — and been performed by ensembles including the English Chamber Orchestra and Bohuslav Martinu Chamber Orchestra, among other ensembles in the United States, Greece, and elsewhere.
Our condolences to Mr. Constantinides to his family, friends, students, and colleagues.
