The basset-clarinet is not to be confused with 
                  the basset-horn, though they are closely related. The 
                  latter is really a type of alto clarinet, midway between the 
                  normal clarinet and the bass, while the former is simply a clarinet 
                  with an extension downwards of several semitones, for which 
                  Mozart is believed to have conceived the two great masterpieces 
                  on this disc. 
                
 
                
Specific differences to the normally heard 
                  versions of the works are not that noticeable, though they are 
                  in fact quite numerous; in the first movement of the quintet, 
                  for example, there is the passage of quaver figuration in the 
                  clarinet part that starts at 5:36, where several of the lowest 
                  notes would be outside the range of the clarinet. Similarly, 
                  in the concerto, there is the section at 2:58, where once again, 
                  notes lower than the normal range are heard. There is a pleasing 
                  logic in all of these adjustments, and they in no way alter 
                  the familiar course of the music. 
                
 
                
On the other hand, the tone that Jean-Claude 
                  Veilhan produces may be less acceptable to many ears. There 
                  is no doubting that he is an accomplished and highly musical 
                  player, but his basset clarinet has a slightly throaty quality, 
                  and doesn’t sing with the mellifluous ease that modern ears 
                  are used to. Tone is not as even, either; one is occasionally 
                  slightly uncomfortably aware of shifts in register. For me, 
                  this was not a great problem, but others may find it so. 
                
 
                
Certainly the music is given performances of 
                  great character. Tempi in the quintet are on the brisk side, 
                  though the larghetto retains its tranquillity, and the 
                  menuetto has the benefit of an urgent sense of forward 
                  movement. The concerto suffers from a rather idiosyncratic recording. 
                  The acoustic is boxy, and the microphone(s) is(are) very close, 
                  with practically no balance distinction between soloist and 
                  orchestra. This takes a bit of getting used to, but I found 
                  it grew on me, especially as the quality of playing in the small 
                  accompanying ensemble is generally of high quality. More worrying 
                  is the seeming clumsiness of the basset-clarinet as compared 
                  with the clarinet. Many passages of intricate figuration sound 
                  distinctly awkward in Veilhan’s hands, detracting from the elegance 
                  of the work. I don’t believe that this is lack of sensitivity 
                  or technique on his part, however, more in the nature of the 
                  longer, heavier instrument. 
                
 
                
But these are performances worth hearing, if 
                  only for the unusual experience of the instrument for which 
                  this music was originally intended.
