This Deutsche Grammaphon disc was originally released as part of the "20/21" series of contemporary music recordings, but as that series has now ended (apparently because only a limited number of the expensive paper boxes were produced) it thankfully appears again in the new Grand Prix series. It contains three pieces by Pierre Boulez from the last quarter of the 20th century. Boulez's recent expansions of his venerable pieces from the 1950s ("Le Marteu Sans Maitre") and 1960s ("Pli Selon Pli") are increasingly overlong and plodding, but from this disc it's clear that the fresh pieces he's written lately are full of great energy and momentum, alongside the gorgeous warmth of mid-frequency sounds that has always been a hallmark of Boulez's art. This music uses all twelve tones, but it is never "dissonant", its formal scheme may be too complicated for some to grasp completely, but it's never noisy.
"Sur Incises" (1996/1998) for three pianos, three harps, and three percussion instruments is a two-movement expansion of Boulez's earlier "Incises" for solo piano, a three-minute virtuoso piano solo that I prize even more than Ligeti's Etudes. Boulez had considered writing a piano concerto, but was frustrated that most of the orchestra can't match the piano's speed. So, in a nod to Stravinsky's "Les Noces", he added two more pianos, and brought in instruments which can mirror certain qualities of the piano. The form of the music consists of alternating tempos, one slow and meditative where one instrument often takes a spotlight while others accompany, the other wild and energetic where all nine instruments compete virgourously, and throughout the original composition for piano solo can be heard underneath. "Sur Incises" requires great virtuosity, and is surely one of the most challenging pieces of contemporary music. The soloists of the Ensemble Intercontemporain handle it flawlessly. All in all, a fantastic piece. No wonder it won the Grawemeyer Award in 2001. I should mention that if you really dig "Sur Incises", there's a recent DVD in the Juxtapositions series that contains a very layman-friendly lecture by Boulez on the piece, as well as a complete performance by the same soloists as here.
"Messagequisse" for seven cellos (1977) dates from two decades before either of the other two pieces on this disc, but fits in very well nonetheless. Written for a solo cello backed up with a small cello ensemble, the piece begins with a slow mournful melody played on the primary cello with pizzicato accompaniment by the others. A very furiously bowed section follows, a contrast with much the same effect as in "Sur Incises". My only complaint is that it's a short piece, and it's really over before one has much time to come to grips with its intriguing soundworld. The following "Anthemes 2" for violin and electronics (1997) is much longer, an electronic expansion of a work originalyl for violin solo. In much the same way as Nono's "La lontanza...", here we have a violinist played against himself, and the direct "realness" of the living soloist stands in eerie opposition to the electronic sound. There's no ultimate form here, rather the work consists of a series of brief episodes, but each new exploration follows the last in a harmonious manner. For some reason, I'm especially tempted to compare this work to Unsuk Chin's "Xi" for electronics, but there's a much more human touch.
Along with the wild flute concerto "...explosante-fixe...", available on another DG disc, the material here makes for a great introduction to Boulez. If you've heard that he's only a snobbish intellectual who doesn't understand the concept of fun, these pieces will quickly show you that his art is entirely in tune with a desire to rock out.
