A "new" Beethoven piano sonata, reconstructed from fragments, was premiered last weekend in Amsterdam. There is all kinds of discussion as to its worth. I have not had time to review it all in depth but I get the idea that people are arguing whether he intended the music as a solo piano sonata or as something else, say a string quartet.
British author and musicologist Norman Lebrecht, friend to the Gusto Blog, discussed the piece briefly.
The score is available here to interested pianists.
