All three of the works included here derive from some previous piece or thematic idea, but it's not necessary to know any of the originals to appreciate what Boulez has done. In one sense at least--his concern for the more sensuous aspects of sound--Boulez remains profoundly French. He has taken the typically French polished surface and exquisite sense of sonority a step further, though, to include the interaction of his musical fabric with the acoustic space in which it will be displayed. For example, the electronics that create the environment inhabited by the solo violin in Anthèmes 2 take their material from the soloist as well, reflecting his sound back on him in an ongoing melodic interplay. Messagesquisse does much the same thing, only without the gadgetry: here the cello soloist confronts six additional cellos. The result may not sound much like Villa-Lobos in Bachianas brasileiras mode but it surely takes a similar visceral delight in the rich variety of sounds available to a virtuoso ensemble of cellos.

Finally there's Sur Incises, a magnificent piece "about" the myriad ways the sound of three pianos can be extended by adding three harps and three percussionists (playing mallets and other tuned instruments) to the basic ensemble. Stravinsky's Les Noces is certainly in the background here, and even more to the point, Bartók's Sonata for Two Pianos and Percussion. Indeed, after the calm opening, some real Bartókian fireworks give the music genuine passion and expressive urgency. Difficult? Yes, but rewarding too. The performances, under the direction of the composer, presumably give him everything that he wants. I can imagine more warmth at certain moments from the cellos, and maybe an even more savage attack on Sur Incises, but there's no point in complaining about the air when there's nothing else to breathe. Enjoyable, even wonderful, but not for everyone. [11/11/2000]
