Years ago I switched on my car radio in the middle of a work 
                  for cello and piano, and couldn’t decide who the composer was. 
                  It sounded a bit like Beethoven; but then it didn’t – too much 
                  frothy passage work. Maybe Mozart? No, a bit more oomph than 
                  that. It turned out to be one of the Mendelssohn cello sonatas. 
                  
                  
                  Mendelssohn’s cello and piano output comprises two Sonatas, 
                  the Variations Concertantes, an Assai tranquillo, and a late 
                  Song without Words. All this comes to about an hour of music, 
                  fitting nicely onto a CD. It is played here by a young Israeli 
                  cellist, Emanuel Gruber, with his regular duo partner Arnon 
                  Erez. 
                  
                  The current recording begins with the Variations. Where a grand 
                  piano is involved it will often overpower a cello, but with 
                  this duo it is the other way around. Emanuel Gruber seems reluctant 
                  to cede the melodic interest to his partner, even when the cello 
                  is clearly accompanying the piano. Arnon Erez compounds this 
                  tendency by the skill with which he recedes into the background. 
                  This is highly accomplished playing, but lacks the give and 
                  take that marks the best chamber music performance. 
                  
                  The first Sonata begins at a fairly brisk tempo, a little unyieldingly 
                  maintained. Again the playing of the duo is very clean, but 
                  together with the slightly rigid tempo there is a lack of dynamic 
                  variety. This gives a somewhat relentless feeling. There is 
                  a bit more dynamic shading in the Andante, where Emanuel Gruber’s 
                  legato playing is eloquent; I felt he could have made more of 
                  some of the phrases. The final Allegro Assai opens in a placid 
                  mood, which soon gives way to brilliant episodes with plenty 
                  of interplay between the partners. Gruber and Erez perform this 
                  efficiently, but without much light and shade. I particularly 
                  felt that Gruber could have varied his tone production more 
                  by using different amounts of bow weight and varying its proximity 
                  from the bridge. 
                  
                  The Song without Words again receives a smooth and controlled 
                  performance; the mid-section could have been a bit more passionate. 
                  Technically, Gruber’s legato is extremely impressive; his bow 
                  changes are beautifully smoothed over. Interpretively, however, 
                  I felt that he extends his phrases to the point of monotony. 
                  The second Sonata suffered from the same faults as the first, 
                  with the cello being over-dominant and the rhythms unyielding. 
                  The duo’s sound is hampered by what sounds like a very dry acoustic, 
                  which robs Gruber’s fine 1706 David Tecchler cello of tonal 
                  interest. 
                  
                  Christophe Coin and Patrick Cohen recorded these works in 1989 
                  - released by Oiseau-Lyre in 1992. This was one of the earliest 
                  recordings of the Mendelssohn cello sonatas, and as far as I 
                  know the first to use a fortepiano. Coin and Cohen have a genuine 
                  chamber music partnership, each receding into the background 
                  to accompany the other as required. They also really dig into 
                  the works in a passionate way. Timings are slower, by almost 
                  5 minutes in each of the sonatas; this suggests a more fleet 
                  but also more superficial approach on the part of Gruber and 
                  Erez. Although Coin’s instrument is by an anonymous maker, he 
                  achieves far more tonal and dynamic variety than Gruber. A lot 
                  of this stems from his bowing, which concentrates less on achieving 
                  a perfect legato than on advancing the musical argument. Cohen 
                  and Coin’s performances are more dramatic than Gruber’s and 
                  Erez’s, much better recorded and more musically satisfying. 
                  
                  
                  I wish I could be more positive about this recording; both players 
                  are obviously considerable artists who have a feeling for Mendelssohn. 
                  Unfortunately their approach emphasises this composer’s fluency 
                  and brilliance at the expense of his more substantial qualities. 
                  Gruber and Erez nail the notes with precision, but miss the 
                  soul behind them.
