Iannis Xenakis (1922-2001) is one of the most important composers of the 20th century avantgarde whose influence on music can be traced to the present day – not only in the world of conservatory-trained composers but also in various streams of current non-academic underground aesthetics such as experimental electronic music, noise and industrial. After he arrived in Paris in 1947, Xenakis not only studied composition with Messian and later became a member of the famous GRM (Groupe de recherches musicales).
His compositions often are based on mathematical principles which give his music an unprecedented aesthetic and “shocking otherness” (The Guardian).
