Iancu Dumitrescu

He received a master's degree in composition in Bucharest, where his teachers included Alfred Mendelsohn.

In 1976 he founded the Hyperion Ensemble, which he describes as "a multimedia group dedicated to experimental music".

Several of Dumitrescu's early works for solo contrabass were recorded by the noted avant-garde bassist Fernando Grillo.

In its emphasis on long tones that undergo transformations of timbre, Dumitrescu's music can be loosely grouped with that of Italian composer Giacinto Scelsi and with the spectral music of fellow Romanian Horațiu Rădulescu and the French composers of the spectral school.

[2] Dumitrescu was married to fellow composer Ana-Maria Avram (1961–2017); they have more than 20 joint CD releases on their Edition Modern label.
