The Japanese known only by a single name offers two long-established Xenakis masterpieces. Those who already know Pléïades (1978) will wonder how, since these four movements (three of them for particular timbre groups) are intended for an ensemble of six. The answer? Multitracking. No need for such ingenuity in Rebonds (1987-89). These are meticulous and muscular performances, at once elemental and elegant. Brilliant.
