Composed over a period of twenty years, these four electroacoustic pieces by Ivo Malec reflect the richness of his sonic universe and reveal the unique power of his musical writing. His strength lies in an ability to harness emerging sounds and techniques (ranging from complex editing to early computer music and electronic synthesis) and develop them through an exploratory approach, giving rise to musical ideas of rare clarity. This sense of determination, not only in terms of the future of sounds but also of musical forms, is what makes Ivo Malec an essential composer on the contemporary music scene and a key figure in the GRM's repertoire.
