Gyorgy Ligeti was, along with Karlheinz Stockhausen, Iannis Xenakis and Pierre Boulez, one of a group of composers which revolutionised postwar music.
Rejecting classical musical forms and creating often sparse and atonal works, they continually withstood the derision heaped upon them by generations of critics.

Appointed Professor of Harmony, Counterpoint and Formal Analysis at the Budapest Conservatory in 1950, he fled the country in the wake of the Soviet invasion six years later.

Perhaps his most notable, certainly his most famous, piece was
Atmospheres from 1960.
This work featured, along with Ligeti's
Requiem and
Lux Aeterna, on the soundtrack of Stanley Kubrick's film
2001: A Space Odyssey.

Volumina and
Harmonies for organ, and the devilish
Continuum for harpsichord.
For those of you less familiar with classical music, one of Ligeti's students, Andrew Powell (who also studied with Stockhausen and Boulez) was one of the essential collaborators on the Alan Parsons Project's first album,
Tales of Mystery and Imagination. There are flashes of the Ligeti influence in the tracks
The Tell-Tale Heart,
The Fall of the House of Usher(of course), and
Psychobabble(from the later
Eye In The Sky album)
