This cd contains a neglected Xenakis masterpiece, IDMEN A/B (1984), for chorus and percussionSSS. It sustains the typical, classic, Xenakian hallmarks, but comes off as his most breezy, "feel good" piece. Obviously, the delicacy of the writing for multiple percussionists has something to do with it, but also, this is a mighty choral work utilizing all the favorite X tricks. I am really at a loss for words as to it's beauty. The fourth mouvement is the most perfect realization of Xenakis's "pelog" scale (which opens up JONCHAIES), very tropical, with the great Pacific vistas in mind. The percussion mouvements make for interesting comparison to the other piece on the cd.
