A few months ago, when 
          reviewing a recording of Grisey’s last completed work (Quatre 
          chants pour franchir le seuil [1997/8]), I mentioned his big 
          cycle Les Espaces Acoustiques composed between 1974 and 
          1985 of which I found this recording while browsing through the shelves 
          of a record shop in Brussels. 
        
 
        
Les Espaces Acoustiques was not originally 
          planned as a cycle. In fact, Grisey composed Périodes 
          for seven players (1974) as the result of a commission from the Ensemble 
          L’Itinéraire which gave the first performance in Rome in 1974. 
          The piece, scored for flute, clarinet, trombone and string quartet (no 
          cello, but a double bass), is a suite of clearly characterised episodes 
          in the last of which Grisey experimented with a technique he later developed 
          more fully and which is generally known now as "spectral music". 
          In 1975 he completed Partiels for 18 instruments, a commission 
          from the Ministère des Affaires Culturelles, that was again first 
          performed by L’Itinéraire conducted by Boris de Vinogradov. Only 
          then did he began to think about a large-scale cycle for instrumental 
          forces of increasingly larger number. He thus decided that the first 
          piece of the cycle should be for a solo instrument; and, since the viola 
          plays a prominent part in Périodes, he chose to 
          compose the Prologue for solo viola (1976). The other 
          pieces were written when commissions came the composer’s way, though 
          always keeping in mind that they were to be part of the cycle, and should 
          thus maintain some structural logic with any of the other components 
          of Les Espaces Acoustiques. Thus Modulations 
          for 33 players (1976/7), commissioned by the Ensemble InterContemporain 
          and dedicated to Messiaen on his 70th birthday, was first 
          performed in 1978 conducted by Michel Tabachnik. Transitoires 
          for orchestra, commissioned by the Symphony Orchestra of Sicily, followed 
          in 1980/1 and was first performed in Venice in 1981. Finally, Epilogue 
          for four horns and orchestra completed the cycle in 1985. Its first 
          performance by the BBC Symphony Orchestra conducted by Peter Eötvös 
          took place in Venice again in 1985. 
        
 
        
All pieces from the cycle, save Epilogue, 
          may be performed separately. Transitoires and Epilogue, 
          however, must be played together (in that order, of course!). Nevertheless, 
          the whole cycle may be (and is better) performed complete and has already 
          been played as such on several occasions, as it was during the Ars 
          Musica festival in Brussels in 1993. It goes without saying that 
          a complete performance of Les Espaces Acoustiques exerts 
          a more telling impact since the several pieces are connected in one 
          way or another, the more so after the completion of Prologue 
          that acts as a red thread all through the later stages of the cycle. 
          A complete performance, however, poses certain problems of organisation 
          which are mostly solved by the interval during the third and fourth 
          pieces. 
        
 
        
So, the Prologue opens unobtrusively, 
          one single note being slowly explored. Intervals then progressively 
          widen whereas the harmonic spectra enrich the instrument’s palette. 
          This free, somewhat improvisatory music merges almost unnoticed into 
          Périodes in which strings are clearly prominent. 
          Similarly, the final section of Périodes is, as 
          it were, engulfed and amplified by the richer textures of Partiels. 
          This piece, however, ends rather dreamily, in the bass register and 
          at a low, almost inaudible dynamic level. Thus, considering the virtual 
          impossibility of achieving complete silence in concert halls, the very 
          end of Partiels is "accompanied" by various 
          noises produced by the players, not the instruments, who drop their 
          scores on the floor, shuffle their feet, cough and the like. Though 
          this is generally discreetly done (especially in this recording), I 
          find this "gimmick" completely irrelevant and a slight miscalculation 
          (and the only one in the whole cycle) on the composer’s part for the 
          tension accumulated in the course of the first three pieces and its 
          quiet resolution at the end is gripping enough to keep the audience 
          silent for a few seconds. 
        
 
        
The second "panel" (Modulations, Transitoires 
          and Epilogue) is scored for larger forces although 
          Modulations is for medium-size orchestra. Modulations 
          is mainly a study in orchestral textures that ends with a long crescendo 
          leading into the richer sound palette of Transitoires. 
          The latter is almost some sort of tone poem evoking in turn mighty natural 
          phenomena (for the present writer, at least), craggy landscapes and 
          wide rarefied spaces. Some of the more heavily scored sections call 
          forth images of big lava waves drifting down the volcano’s slopes, stopped 
          or slowed-down by protruding rocks and drifting along with lessened 
          intensity whereas the nocturnal final section has the viola musing over 
          some material from Prologue, supported by a delicately 
          scored bell-like accompaniment. It slowly merges into the Epilogue 
          first accompanied and later engulfed by woodwind rippling figures. That 
          is where the four horns take over, first echoing, then extending the 
          viola’s material. The final horn flourishes are punctuated by isolated 
          bass drum strokes. 
        
Les Espaces Acoustiques is a major achievement 
          of late 20th Century music; and, no doubt, Grisey’s most 
          powerful statement. It also illustrates Grisey’s progress and increasing 
          mastery of his technique over these years while demonstrating the composer’s 
          unfailing aural imagination and ability to structure his works on a 
          long term basis. In Les Espaces, Grisey uses a wide-ranging 
          array of techniques, discarding neither consonance nor harmonically 
          enlarged "spectral" fields; but he always sees that the works 
          of the cycle have a firm, coherent basis often achieved through the 
          recurring use of long-held pedal notes or rhythmic ostinati. 
          His strictly intellectual conception never excludes some vivid aural 
          imagination, which is one of his most endearing qualities; and, no matter 
          how technically complex it may be, Grisey’s best music strongly communicates 
          by its sheer physical, almost elemental strength. This is the sort of 
          music that Varèse would have written, had he lived in the 1980s. 
        
 
        
The performances are superb: carefully prepared, polished 
          and committed, bringing out the remarkable expressive power of this 
          major cycle by one of the finest composers of his generation whose untimely 
          death was – and will remain – a great loss.
