Pli selon pli;

Pli Selon Pli (Fold by Fold) is a portrait of Mallarmé, whose poems are set in fragmented fashion throughout the work's five movements, which Boulez rewrote and added to until they assumed final form in 1989. His 1969 Sony recording had an icy, frozen surface and a general air of impenetrability. Age may have mellowed the maestro, for this version, while still challenging, is more accessible. Textures are more finely drawn; the delicate colorations of winds and plucked instruments, including a mandolin, are more sensuous; and a traditional French sensibility is more obvious. The singer, soprano Christine Schäfer, is more communicative, too: her high notes are smoothly produced, her lines seamlessly woven into the orchestral fabric. The voice is effectively an instrumental line in the work's structure, and texts are fragmented into discrete words and syllables. For all their importance, they occupy a relatively limited portion of the piece's 70 minutes. The crack instrumentalists of the Ensemble Intercontemporain are masters of Boulez's style, and it's hard to imagine a better performance of this modernist milestone. --Dan Davis
