An exhilarating Xenakis programe, built around works for soloist and ensemble. Most of the soloists are from the acclaimed International Contemporary Ensemble led by their resident guest conductor, Steven Schick. 'Zythos' and 'O-Mega' are among Xenakis’s final compositions. In the Xenakis oeuvre these constitute a new and plaintive percussion music. Yet there is a strange power in these stark landscapes. In 'Zythos,' long trombone lines are wound round the threading of six marimba parts. It receives its first recording here, featuring trombonist Benny Sluchin of Ensemble Intercontemporain. 'O-Mega', a fitting name for Xenakis’s final work, is a short offering for percussion soloist and chamber group.
