György Ligeti (28 May 1923 – 12 June 2006)

György Sándor Ligeti (/ˈlɪɡəti/; Hungarian: Ligeti György Sándor, pronounced [ˈliɡɛti ˈɟørɟ ˈʃaːndor]; 28 May 1923 – 12 June 2006) was a Hungarian-Austrian composer of contemporary classical music. He has been described as "one of the most important avant-garde composers in the latter half of the twentieth century" and "one of the most innovative and influential among progressive figures of his time". Restricted in his musical style by the authorities of Communist Hungary, only when he reached the west in 1956 could Ligeti fully realise his passion for avant-garde music and develop new compositional techniques. After experimenting with electronic music in Cologne, his breakthrough came with orchestral works such as Atmosphères, for which he used a technique he later dubbed micropolyphony. After writing his "anti-anti-opera" Le Grand Macabre, Ligeti shifted away from chromaticism and towards polyrhythm for his later works. He is best known by the public through the use of his music in film soundtracks. Although he did not directly compose any film scores, excerpts of pieces composed by him were taken and adapted for film use. The sound design of Stanley Kubrick's films, particularly the music of 2001: A Space Odyssey, drew from Ligeti's work and also contained pieces by other classical composers. (From Wikipedia.
