I cannot agree with a previous reviewer that the playing is dispassionate and "clinically correct" (what an insult!) nor that the recorded sound is cold and antiseptic. The sound is certainly more analytical than lush (little echo) but, in my opinion this suits this music. I find no fault with this aspect of the recorded sound. What does however bother me is that the violin is so under-recorded in comparison with the piano, although Baradi plays with considerable musicality and subtlety. I think that this is the problem and not, as JSA writes, the violin he uses. One could argue that it is the piano which leads in most of the sonatas, as reflected in Beethoven's labelling them as sonatas for piano and violin and not vice versa. Frequently the violin is merely accompanying the piano. In addition, in this particular case it seems to me that Clara Wurtz is definitely the dominant musician. She plays her part with great energy and drive - not in the least bit merely "clinically correct."
I have discovered that there is nearly always a problem balancing these two instruments in performances using a modern piano. A Steinway is quite simply much louder than the instruments used in Beethoven's day and almost invariably drowns the violin. On recordings this is mostly adjusted. Interestingly enough, when played on period instruments this problem does not exist. I have heard one live. Both piano and violin around 1800 were quieter, but it was the piano in particular, which was a lot softer. For a recording which illustrates this point, listen to Midori Seiler and von Immerseel in the Beethoven sonatas or Mullova and Bezuidenhout. I am not talking about the quality of the interpretation, merely the balance between the instruments. Whether you like HIP or not is up each listener personally.
So, all in all I think that JSA has been too severe in his or her criticism. May I give a recommendation: Try the new set with Leonidas Kavakos and Pace on Decca. Here the balance is ideal, although played on a Steinway and a modernised Stradivarius.
My comparisons include Kremer/Argerich, Capucon/Brially, Ibragimova,Tiberghien, Kavakos/Pace and Faust/Melnikov - all complete sets as well as Mullova/Bezuidenhout (single CD) and excerpts from Midori Seiler/von Immerseel.
