This music is very different from Ligeti's mostly static soundscapes of the 1960s ("Atmospheres," "Lux Aeterna" et al.). The rhythmic complexities are amazing: Ligeti cites the polyphony of African music, the player-piano inventions of Conlon Nancarrow, and the jazz pianism of Thelonious Monk and Bill Evans as influences. The motoric power grabs you right away, and the pieces are so vividly descriptive I almost think I could guess what inspired them without knowing their titles. "Vertige" for instance with its fast and queasy up-and-down motion; "Desordre" with its dense layering and extreme violence; "Galamb Borong" (2 pseudo-Javanese words) which evokes the sound of the gamelan; "L'escalier du Diable", a spiral staircase that goes nowhere fast; "Infinite Column", a 2-minute rocket into the stratosphere.
This recording by Pierre-Laurent Aimard ranks just behind Glenn Gould's second assault on the "Goldberg Variations" as my favorite solo piano record.
