ABSTRACT
As Xenakis approached his seventieth birthday in 1992, there was a flurry of celebratory activity. Though suffering from ill health,1 he marshalled his energies to produce, within the space of approximately one year, five major orchestral scores. For our purposes, this peak of activity serves to launch the final period of his career, leading to 1997, the date of his last composition. There is still a great deal of variation to be found in this music, in spite of a general sense of restraint and relative simplification.
