Ivo Malec was born in Zagreb, Croatia. In 1959, he settled in France and joined Pierre Schaeffer in what was to become the GRM (Groupe de Recherches Musicales) one year later. When he arrived in Paris, Malec was already a fully equipped composer with a number of works to his credit, including a piano sonata (1949), a cello sonata (1956) and a symphony (1951) as well as several vocal works. He however considers his works written after 1960 as his first mature compositions. His work at the GRM was to prove extremely fruitful for his later musical progress.
