As an architect and mathematician, Iannis Xenakis brings an unusual eye to bear on his compositional ear. He rejected twelve-tone composition decades ago, instead pushing the envelope further on determinate numbers and sounds and generating a broader palette of available sounds. Graphical notation has been one of Xenakis's chief means of expression, allowing him to script sharply sliding glissandi and what he calls non-octave scales. This 2-CD set collects three string quartets and the busy, aching
Akea, Xenakis's quintet for piano and strings. The unsurpassed Arditti String Quartet plays the ensemble pieces, and then farms out constituent members to play the solo and duo pieces. Pianist Claude Helffer creates pointed havoc on his three solo appearances, offering spare tones and dense steam alike. When playing with the Ardittis, Helffer makes himself central to the hard punch and slightly mad--extremely unconventional drama.
