Ligeti: Atmosphères

Ligeti: Atmosphères
リゲティ:　「アトモスフェール」（Japanese）

This piece is very famous, since it was used in the "2001: A Space Odyssey." Even people who don't like 21th classical music also know this piece.
The most remarkable feature of the piece is the sound of "tone clusters."
I think that Ligeti made Atmosphères more attractive, by using tone clusters.

Luciano Berio: Sequenza III for female voice (1965)

Luciano Berio: Sequenza III for female voice (1965)
ルチアーノ・ベリオ：女声のためのセクエンツァIII　(1965) (Japanese)

I enjoy enjoy listening to this piece without any musical analysis, although this piece is "avant-garde." That is to say, my heart is deeply attracted to the wourld of the piece, even if the musical expression of the piece is not ordinary. In traditional classlical music, songs for females are beatiful in many cases. However, The "Sequenza III" pursuits verious expressions of female voice rather than beatiful expressions.
Probably, at first, you may be surprised at the voice expression at his piece.
Especially, the voice of Cathy Berberian  (the following YouTube)  may leave strong impressions.

Iannis Xenakis: Evryali

Iannis Xenakis: Evryali
ヤニス・クセナキス：エヴリアリ (Japanese)

Evryali is a piece for solo piano composed by Iannis Xenakis.
Many critics analyzed and wrote various reviews about this work. However, before reading the reviwes about it, I would recommend that you listen to this music first.
I think that, when we listen to music, your own impression about the music is most important. I think that reviews written about by others may be helpful for studying music, but your own impression about music can be obtained by yourself.
Fortunately, in additon to sound, the following YouTube shows the score of "Evryali." So, you can acquire a broad grasp of this music.

After you listen to the sound of "Evryali,",  I would recommend that you read articles such as Wikipeida　”Evryali”.
