Guerrero left a fairly considerable output mainly consisting 
                  of chamber works of which the backbone is the substantial cycle 
                  Zayin composed between 1983 and 1997. There’s 
                  also a handful of impressive orchestral works among which Coma 
                  Berenices (1996) may be singled-out as one of his most 
                  inventive and gripping. Incidentally I reviewed a recording 
                  of his orchestral music some time ago (Col 
                  Legno WWE 1CD 20044). At the time of his death he was seemingly 
                  going through some existential crisis that had led him to complete 
                  his orchestration of Iberia. His output is of 
                  substantial quality in spite both of the rather small number 
                  of works and their generally short duration. 
                  
                  The disc under review presents his complete chamber output with 
                  one exception. Zayin - the entire cycle - has 
                  been recorded by the Arditti String Quartet on Almaviva DS-0127 
                  and is well worth the search. The only work that is missing 
                  here is Op.1 Manual (1976) for piano that might 
                  have been included here at least for completeness’ sake. As 
                  can be seen from the above details all the works recorded are 
                  fairly short, but each is packed with substance. Another characteristic 
                  of Guerrero’s music is to be found in the often unusual instrumental 
                  combinations used. From this point of view, the compact and 
                  relatively unproblematic Concierto de cámara (“Chamber 
                  Concerto”) is scored for almost conventional instrumental forces: 
                  flute, bass clarinet and string quartet. It may also be one 
                  of his most readily accessible works were it only because the 
                  composer briefly alludes to cante jondo although filtered 
                  through the composer’s own lens. Another source of inspiration 
                  is reflected in the astronomical titles of some of his works: 
                  Coma Berenices, Delta Cepheis and 
                  Hyades. 
                  
                  Delta Cepheis is for two clarinets and string 
                  trio. In his excellent insert notes Stefano Russomanno rightly 
                  remarks that this piece may be regarded as a transitory work 
                  in Guerrero’s late output. Certain features heard in the music 
                  point towards characteristics found in his final works such 
                  as the orchestral work Sáhara (1991) and to Hyades 
                  (1994). The music, however, sounds to me as vintage Guerrero. 
                  As such, it is redolent of Xenakis or Birtwistle without being 
                  imitative. 
                  
                  Vâda for two sopranos and ensemble (flute, oboe, 
                  bass clarinet, percussion/two players and string quartet) was 
                  written as part of a commission by the City of Valladolid to 
                  celebrate the poet Jorge Guillén. Guerrero’s work must surely 
                  have surprised more than one in the audience for, although he 
                  used a poem by Guillén, his setting completely deconstructs 
                  the text beyond recognition. This short work displays an extraordinary 
                  energy within its short time-span and leaves one with a deep 
                  feeling of unease redeemed by the sheer exuberance of the music. 
                  Compared to this rather enigmatic work, Ars Combinatoria 
                  is almost straightforward. It is scored for a somewhat unusual 
                  wind sextet (piccolo, oboe, contrabassoon, horn, trumpet in 
                  D and trombone) in which trumpet and trombone play muted and 
                  the horn stopped. The music perfectly reflects the implication 
                  of the title in that it moves from the simple to the most complex. 
                  So, the work opens with an oboe solo followed by an astonishing 
                  duo shared by contrabassoon and trombone, later a trio for horn, 
                  trumpet and trombone and the whole group eventually joins for 
                  the final section. The global effect may – to some extent – 
                  be compared to what Michael Tippett did in the first movement 
                  of his Concerto for Orchestra; but the most remarkable 
                  thing about it is how well the instrumental sounds blend. 
                  
                  The comparatively early Anemos C of 1976 is scored 
                  for a fairly traditional wind ensemble (two flutes, two oboes, 
                  two clarinets, two bassoons, two horns) and percussion. This 
                  is the sort of ensemble that Varèse might have used and the 
                  music of this early piece is certainly indebted to Varèse and 
                  – again maybe – to Xenakis. The impact is much the same with 
                  massive blocks of sounds in the outer sections and heavy punctuation 
                  from the percussion framing a more flowing central section. 
                  Anemos C is undoubtedly one of Guerrero’s finest 
                  achievements and a work that already displays most of his music’s 
                  characteristics. 
                  
                  In the early 1990s Guerrero showed some interest in electro-acoustic 
                  music and apparently composed an electro-acoustic work Rigel 
                  in 1992. The otherwise well-informed insert notes do not tell 
                  us whether Rigel was integrated into Hyades 
                  or whether the electronic part of Hyades was composed 
                  especially for this work. This, however, is of marginal importance 
                  when considering the end result. Again, Guerrero’s liking for 
                  unusual instrumental combinations is much to the fore here in 
                  that Hyades is for bass flute, trombone, double 
                  bass and electronics. The work opens with soft electro-acoustic 
                  music suggesting some wide-open space. About halfway into the 
                  piece the instruments come in, their dark sounds in full opposition 
                  to the soft, almost ethereal electro-acoustics creating a remarkable 
                  ‘soundscape’ that may suggest some far-off constellation. In 
                  my earlier review of the Col Legno disc of Guerrero’s orchestral 
                  music I mentioned that Coma Berenices was really 
                  “Music of the Spheres”, if such a thing ever existed. Now, the 
                  same might be said of Hyades; it achieves the 
                  same impact of mysterious, wide-open space thanks to the composer’s 
                  acute ear for arresting sonorities. 
                  
                  Guerrero’s music is no easy listen. It demands repeated hearings 
                  to make its full impact but the rewards are plentiful. The composer’s 
                  inventiveness and aural imagination are such that one is carried 
                  along through the music’s sheer energy and exuberance. These 
                  performances by the Grup Instrumental de València are just superb 
                  and are very well recorded. Joan Cerveró and his colleagues 
                  offer immaculate, well prepared and committed readings of these 
                  demanding, but ultimately highly rewarding scores. I also want 
                  to single out the excellent and detailed insert notes by Stefano 
                  Russomano. 
                  
                  This is a magnificent release that definitely deserves wider 
                  exposure. Guerrero’s powerful, gripping and often beautiful 
                  music is far too good to pass ignored.
