"Horatiu Radulescu was a Romanian-French composer, best known for the spectral technique of composition. Radulescu's spectral techniques, as they evolved through the 1970s and beyond, are quite distinct from those of his French contemporaries Gérard Grisey and Tristan Murail. His compositional aim, as outlined in his book Sound Plasma (1975; see Sources) was to bypass the historical categories of monody, polyphony and heterophony and to create musical textures with all elements in a constant flux. Central to this was an exploration of the harmonic spectrum, and by the invention of new playing techniques to bring out, and sometimes to isolate, the upper partials of complex sounds, on which new spectra could be built."-Wikipedia
