Last month [11th January 2010], i had the third Sonata in my highlights by these two, now it's the turn of the second, and i feel my thoughts there are mirrored here, Mutter and Weissenberg don't seem entirely in unison, like two people on a tandem with different ideas of where to go!, but they're still fascinating to listen to, i wonder how much time these two spent on these Sonatas, also i feel that Weissenberg and his Piano is just pushed back in the mix slightly, making Mutter more prominent, and not giving an equal footing to both instruments, certainly Mutter is on the front of the tandem!.
Well i must say i enjoyed the middle movement, a nice opening tone from Mutter, which Weissenberg mirrors [0:39], there's a nice lilt in Mutters playing [1:17-1:25], nice impassioned playing on the Violin [2:02 onwards], which becomes becomes stronger and stronger [3:03-3:48], and sweeter too, and i love that pizzicato section [3:48-4:36], though i feel they play it too fast, the lovely coda is so sweet [4:37-5:37] and the whole thing is rounded off by some final pizzicato notes, most enjoyable.
Here she is playing this movement on YouTube.
