It 
                  would appear this disc has sat on the Naxos shelves awaiting 
                  release for a full five years. Perhaps the company does not 
                  think it important. After all, the booklet notes appear to be 
                  their house notes on the original Sextets with the briefest 
                  of addenda regarding the current arrangements.
                Were 
                  it not for the dedicated playing of Matthies and Köhn, it might 
                  be easy to justify this. In fact, the two performances here 
                  demonstrate piano duet playing of the first order. One misses 
                  the true legato of stringed instruments. Right at the very opening 
                  of the first movement of Op. 18 - i.e., the first thing you 
                  hear, is a good example of this. Yet one becomes involved in 
                  the listening experience because Matthies and Köhn make such 
                  a point of following the music's structural contours. Only occasionally 
                  does one feel that this is a obviously a reduction, however.
                The 
                  slow movement is famous in its own right., a series of D minor 
                  variations. It could be grander than Matthies and Köhn see it. 
                  Essentially, one should be made more aware that great things 
                  are afoot, and that is not the case here. Much better is the  
                  Scherzo - Allegro molto, very light, cheeky and jocular, in 
                  a rounded, bearded sort of way, while the finale retains a lovely 
                  sense of flow.
                The 
                  G major, Op. 36 immediately reveals the limitations of the transcription. 
                  An oscillating two-note figure, so appropriate to strings, merely 
                  sounds awkward here. The loss of string colour is also felt 
                  acutely around the eight-minute mark, at which point we really 
                  are listening in black-and-white as opposed to, at least, the 
                  sepia autumnal Brahmsian colours of the string original.
                This 
                  time it is the Scherzo that comes second, a movement in which 
                  Brahms seems to want to imitate the Mendelssohn of A Midsummer 
                  Night's Dream. Matthies and Köhn are at their best in this 
                  movement, with some moments of real magic. 
                If 
                  the Scherzo works as transcription, the same cannot be said 
                  of the Poco Adagio. It is very well played here, but this really 
                  does sound like compromise, the bare lines of the opening, for 
                  example, needing the legato (again) and the intensity that solo 
                  strings can give. The repeated-note gala that is the finale 
                  includes some glittering, delightful playing although, again 
                  because of the reduction, it does seem to go on rather.
                Worth 
                  hearing in some respects, then, not least for the intense musicality 
                  of the Matthies and Köhn team. The recording, by the way, seemed 
                  much better on speakers than on headphones, gaining substantial 
                  depth.
