However prominent as conductor, advocate and theorist the Italian 
                  Bruno Maderna was, his position as a composer remains somewhat 
                  enigmatic. He was born in 1920 and died far too young at the 
                  age of 53. Maderna tirelessly promoted the works of his younger 
                  contemporaries - especially Nono and Berio - in particular and 
                  more generally the very idea of an avant-garde. Yet Maderna's 
                  own music remains at times confounding for its marriage of an 
                  apparent appeal to rebelliousness and a somewhat conventional 
                  sound-world. 
                
That is certainly the case with the four works and arrangements 
                  on this excellent new CD. The quality of the music-making, of 
                  the sound and of the informative - if brief - notes that come 
                  with it make this a CD to be sought out. There are two other 
                  discs currently available which contain Quadrivium; only 
                  one with the concerto for two pianos. Maderna's earlier piano 
                  concerto from 1942 and its arrangement for two pianos are receiving 
                  their first recordings here. They receive exceptionally compelling, 
                  sensitive and sympathetic performances. This recording is taken 
                  from the first performance after the 'rediscovery' of the 1942 
                  concerto at an event in Verona on 10 October 2009. 
                
The defining characteristic of all four works is without doubt 
                  a gentle, tuneful and purposeful percussiveness. This is not 
                  the same as beat. Still less is it merely an interest in percussion 
                  instruments for their own sake on Maderna's part. That said, 
                  there are long and frequent passages in Quadrivium which 
                  almost dwell on the beauty of such pitched and unpitched sounds. 
                  Rather, Maderna translates the almost always latent energy represented 
                  by rhythm and momentum into a fully-controlled and never over-exploited 
                  'pull' between unfolding and at times almost serendipitous or 
                  indeterminate melody. The inevitability of the strike to attain 
                  sound. 
                
Each of the piano soloists and the orchestra in Quadrivium 
                  clearly understand exactly why and how such balance, blend, 
                  and poise are necessary, what they mean, and how to achieve 
                  them. The performances are lively and spirited and hold the 
                  attention from first to last.   
                
Quadrivium is almost as long as the three piano pieces 
                  together. It dates from 1969 and is built - not surprisingly, 
                  given its title - on the number four: four percussionists and 
                  four orchestral groups. As with the piano pieces, the writing 
                  is symphonic and brilliant in character. The brilliance is the 
                  preserve of both soloists and the great presence which the orchestra 
                  has. 'Presence' because Maderna's music often exposes its substance 
                  obliquely as well as deliberately and defiantly. In this case 
                  there's an overt external - though again, oblique - reference 
                  to the four liberal arts: arithmetic, algebra, music and astronomy. 
                
More transparently, four is seen as a magic number in wider 
                  terms - four points of the compass, four seasons. But neither 
                  the music as composed nor the playing, which is of a very high 
                  standard, needs any 'excuse'. Maderna's great achievement in 
                  Quadrivium is to suggest realities, to offer ways in 
                  which they can interact and in which intuition and compositional 
                  imagination inform and are informed by technical rigour. Again, 
                  the way in which the Orchestra della Fondazione 'Arena di Verona' 
                  translates this potentially elusive balance into a plausible 
                  and convincing performance is very pleasing. Similarly the balance 
                  and active interaction between dynamics has been accomplished 
                  very well - even to the extent of translating Maderna's counter-posing 
                  of silence and sound. Credit must also go to conductor Carlo 
                  Miotto for this - and the other successful accounts on the CD. 
                
It's all the more remarkable that Maderna is known to have 
                  reworked and revised particularly the Concerto for two pianos 
                  and instruments to the extent he did. This dates from the 
                  immediate post-war period. It still receives minimal exposure 
                  despite being a beautiful work. It's just as remarkable that 
                  the result is as seamless as it is. It is honoured as such, 
                  as wholly and successfully integrated by Gruppo 40.6. This group 
                  is so named because 40.6 is the number of kilometres between 
                  Mantua and Verona, from which the relatively recently-formed 
                  five person group comes and in which they perform new music. 
                
All in all this CD is something of a small fillip for twentieth 
                  century music in general and that of Maderna in particular. 
                  The standard of playing can only serve to give impetus to the 
                  reinstatement of Maderna's reputation, and appreciation of his 
                  unusual but significant music.
