It is a testament to the size and quality of Hyperion's back 
                  catalogue that the company can run two reissue imprints simultaneously: 
                  Helios and Dyad. The latter, as its name suggests, offers two-disc 
                  box sets, and the deal is two discs for the price of one. Given 
                  that Hyperion discs have always been at the more expensive end 
                  of the market, or rather that full-price means exactly that 
                  from the company, we are still not talking about incredible 
                  bargains here, but an opportunity to hear some of the great 
                  recordings from the label's past is always welcome. 
                  
                  Beethoven's Complete String Trios comprise three opuses, the 
                  Trio Op.3, the Serenade Op.8 and the set of three Trios Op.9. 
                  All were written in Beethoven's early years in Vienna, but none 
                  are conservative or predictable. Beethoven was writing for some 
                  skilled performers, especially in the Op.9 set, and even though 
                  they were all published at the time, he seems to have had little 
                  regard for the conservative tastes of Viennese audiences, or 
                  for the amateur performance market. All of the hallmarks of 
                  the composer's later greatness are here: the traditional forms 
                  extended almost to the point of absurdity, the tangential key 
                  relationships, the virtuoso instrumental writing that always 
                  manages to keep at least one foot on the ground. And there is 
                  a lightness of touch that may or may not be a result of the 
                  composer's studies with Haydn. You couldn't mistake these works 
                  for Haydn though, and while they are recognisably 18th 
                  century they are also clearly looking forward to the stylistic 
                  and technical innovations of the 19th. 
                  
                  Having said that, there is a significant difference between 
                  the quality of the works on the first disc to those on the second. 
                  The latter is devoted to the Op.9 set, and these three works 
                  have a sophistication and maturity that clearly sets them apart 
                  from both the Op.3 Trio and the Op.8 Serenade. Interestingly 
                  they are not any longer than their predecessors, nor is the 
                  thematic density any greater. But the drama in these works, 
                  the profundity of there slow movements and monumentality of 
                  their finales all put in them in a different league. 
                  
                  The performances too are superior on this second disc. The first 
                  disc is also well played, but there seems to be a much greater 
                  unity of intent between the players on the second. All the players 
                  are technically proficient, although the viola sometimes lags 
                  a little behind the violin in terms of dexterity on the first 
                  disc. No such complaints on the second though, were only the 
                  timbre of the different instruments separates them. 
                  
                  The recording quality is good, with the ensemble sounding clear 
                  and crisp throughout. Some may complain about a lack of atmosphere, 
                  such is the clarity of the sound, but you can't have it both 
                  ways. The violin can sometimes sound brittle and icy in the 
                  top register, but I suspect this is a product of the audio. 
                  The cello, on the other hand, sounds wonderful throughout. She 
                  has a real richness in the lower register and a valuable clarity 
                  at the top that really separates the voices in the more closely-voiced 
                  harmonies. 
                  
                  This is an excellent Beethoven recording, but the second disc 
                  of the set is clearly superior, both in terms of the quality 
                  of the music and of the performance. And good as the first disc 
                  is, the disparity between them does somewhat compromise the 
                  logic of the reissue. If we were offered just the Op.9 Trios 
                  at the same price, we would not be losing out very much by not 
                  hearing the Op.3 or Op.8 works. Still, the word 'complete' in 
                  the title is bound to appeal to collectors. I just wonder how 
                  often they are going to listen to disc 1.
