When I first bought this I thought of Ligeti as a distinguished atonal, postmodern composer, but have since discovered that he is much more unique than that description suggests. He is beyond tonality and atonality, and beyond postmodernism. In his own words: "the ironic theatricalizing of the past is quite foreign to me."
Written between 1985 and 1992, the Piano Concerto and Violin Concerto together are supposed to demonstrate the full expressive range of his later works. The Piano Concerto is a whirlwind of rhythmically driven fantasies, created by precise, almost mechanical, colliding cross-rhythms, and twisted, sprightly melodies. The Violin Concerto is just as quirky and jarring, but wilder and more impassioned, less 'mechanical,' more vigorous, and ultimately the highlight of the disc. I find Perre Laurent-Aimard's second version of the Piano Concerto, with the Schonberg Ensemble under Reinbert de Leeuw's, more enjoyable than this recording, but of the two available recordings of the Violin Concerto this seems to be widely considered the better (the only one I've heard).
All of the compositions on the disc demonstrate amazingly effective use of space and time, and advanced virtuosity at the absolute service of artistic vision. Excellent recording.
For me, as a newcomer to modern 'classical' music, this disc demanded some serious listening adjustment, attention and patience, but it was well worth the effort. Judging by the liner notes, a degree in music theory might also have been of great help, but I don't think I am prepared to go THAT far to fully appreciate these remarkable musical/sonic experiences.
