I don't not think there is another thread designated for this type of discussion and sharing. It isn't just for any one particular instrument or ensemble, or even genre; this is for more of a performer's or music "appreciation" thread than a composer's discussion, so I think it's specific name and discussion helps us.

Okay, so I'll start off with a single movement of a great Cello Sonata by Beethoven (No. 3 in A major). Link: J.du Pré - Beethoven Sonata No.3 in A - II.Scherzo (http://www.youtube.com/watch?v=LKgoq16TJLw&feature=rec-HM-fresh+div). I am not a string player, not even close, (maybe a little guitar) but I payed attention to the piano in this. Barenboim, being an amazing pianist and a conductor, his skill and artistry with chamber music is exquisite. Of the many string and piano sonatas out there, Beethoven utilizes BOTH the cello AND piano in his sonatas, this being harder (I feel) for musicians. As most string sonatas in Mozart are more string oriented, the piano is almost an entire accompaniment. But anyway, Barenboim's ear is perfect in this performance, and shows the perfect balance between the play with the piano and the cello. How they both match the A theme is amazing; their balance, yet sheer intensity, is amazing.

I only wish more musicians could match and play together this well-- and by together, I do not mean "in time" yet "in colour."
