The French composer Alsina was born in Buenos Aires (Argentina) in 1941, where he completed his formal studies of piano and theory and went on to study composition on his own.
He began his career as a concert pianist at age 6, with recitals initially in Latin America and then in Europe, in the United States and in Canada.
He also performed as soloist on orchestral programmes conducted by Otto Klemperer, Jasha Horenstein, Manuel Rosenthal, Ernest Bour, Michel Tabachnik, Gilbert Amy, and Semyon Bychkov, among others.
He took an active part as both pianist and composer in the musical programs organized by numerous institutions, including "Nueva musica" (Buenos Aires 1959-64), "Artists-in-Residence" (Berlin, 1964-66), "Center of Creative and Performing Arts" (Buffalo, New York 1967-69); the University of Buffalo (1968) and the Juilliard School (1969).
In 1971 Alsina was awarded the Guggenheim Prize (New York) for his works Uberwindung and Schichten.
Since 1978 he has devoted much time to teaching, in parallel with his composition, and has been invited to give courses as a guest professor at numerous European musical institutions.
He is often invited to sit on the juries of international competitions, and at present holds a professorship in piano at the Conservatoire National Supérieur de Musique in Lyon.
He has written, to date, roughly 100 works, primarily for full orchestra, which have appeared on the programmes of most of the important international music festivals worldwide, including Berlin, Hamburg, Vienna, Donaueschingen, Darmstadt, Tanglewood, Amsterdam, Paris, Royan, Metz, Lille and Venice.
For his fiftieth birthday, the Orchestre de Paris commissioned and performed the composer's Second Symphony (his hundredth work), which has now become part of the orchestra's permanent repertory.
Radio France also honored him with a "Portrait" (consisting of two symphony concerts) highlighting Alsina's work as both a pianist and a composer.
In 1986 Carlos Roqué Alsina was appointed "officier" of the French Ordre National des Arts et Lettres.
