Iannis Xenakis (1922-2001) was a musical master, and as a composer he was good at getting musicians to make a lot of noise – naturally, deeply organized noise! At Lincoln Center’s TullyScope festival in New York while playing,  Les Percussions de Strasbourg were stationed around the hall, so that the audience was surrounded.

“The score, in four movements, probes specific kinds of sound (mixed timbres, metals, keyboards and skins) in a blend of complexity and directness, with persistently repetitive sections offset by unpredictable bursts and sudden changes of direction.” (Listen toperformed “Persephassa” on  Music Online)

Iannis Xenakis was an ethnic Greek, naturalized French composer, music theorist, and architect-engineer. He is commonly recognized as one of the most important post-war avant-garde composers. Xenakis pioneered the use of mathematical models such as applications of set theory, varied use of stochastic processes, game theory, etc., in music, and was also an important influence on the development of electronic music.
