Despite the complexities within the compositions, and also the rigorous demands they make on performers, the impact of Xenakis's music on the listener is always direct. The music is still alive with "the whole agony of my youth and the Resistance", but there is an increasing richness of expression, a spirit of exuberance and exhilaration, a new romanticism, what seems to be a celebration of the sheer joy of music by a composer at the height of his powers and in full command of his medium, his destiny. This production received the quarterly German Record Critics' Award. Spectrum / Guy Protheroe: conductor / Irvine Arditti: violin / Claude Helffer: piano / Penelope Walmsley-Clark: soprano.
