Iannis Xenakis (1922-2001) was one of the leaders of modernism in music, a hugely influential composer, particularly in the later 1950s and 1960s, when he was experimenting with compositional techniques that soon entered the basic vocabulary of the twentieth-century avant garde. He formulated a theory of stochastic music in the early 1950s, co-founded the Groupe de Recherches Musicales in 1958, pioneered the use of computers to compose in 1961.
