La Légende d'Eer (1977-1978) was composed when Iannis Xenakis was in the midst of his far-reaching explorations of mythology and philosophy. Variously inspired by Plato's myth of Er in The Republic, Pascal's Pensées, and even an article on supernovas in Scientific American, this piece transcends programmatic considerations and presents a strange, roiling soundscape that dwarfs Xenakis' earlier electro-acoustic efforts in scope and imagination. This astonishing piece begins with an extended passage of penetrating, shrill tones that break up into unevenly staggered and twittering pulses. These gradually widen into thick bands of gliding microtonal clusters and bulging intrusions of processed noise, harsh percussive attacks, and throbbing ostinati that grow in density and intensity, only to thin out by the end in distant, glassy pitches similar to the opening. The cumulative effect is similar to the immense roar of Xenakis' Bohor (1962), a shimmering congeries of metallic and rumbling tones that, for its time, seemed the ultimate expression of cosmic vastness and chaos.

The piece features many of Ligetis characteristic styles, including:
Micropolyphony, which Ligeti describes as The complex polyphony of the individual parts[,] embodied in a harmonic-musical flow in which the harmonies do not change suddenly, but merge into one another; one clearly discernible interval combination is gradually blurred, and from this cloudiness it is possible to discern a new interval combination taking shape.
Cluster chords, where every note within a given interval is sung simultaneously
A focus on timbre instead of melody, harmony, or rhythm.
The piece can be seen as divided into three distinct parts, as designated by text:
Lux aeterna luceat eis [m.1–36]: The sopranos and altos sing very similar parts in Ligetis characteristic style of micropolyphony. Each part has the same sequence of notes, separated by small time intervals. The tenors enter about halfway through this section, singing in the same range as the women.
Domine cum sanctus tuis in aeternum... [m.37–86]: The basses enter, singing in very high falsetto, showing Ligetis focus on timbre and texture. This is followed by a section where only the mens voices sing, and then the women enter on the text Quia pius es. The sopranos sing Requiem aeternam dona eis in a high register and gradually fade away.
Domine et lux perpetua luceat eis [m.87–126]: The men again sing the text Domine, this time in a more usual register, followed by the womens entrance, the altos in a low register and the sopranos in a high register. All parts gradually fade, and the piece ends with seven bars of silence. György Ligeti: Lux Aeterna](https://i.ytimg.com/vi/W5y1dwVc7O8/mqdefault.jpg)
