a conjectural reconstruction of the originally-intended orchestral finale, whose sketches were later reworked as the finale of the A minor quartet , op.132.
That would be a very nice one, smittims, and such a reconstruction would be based on better assumptions than Dr.Cooper's "Beethoven 10".
Another late work I'd like to hear in its original form is the introduction for the string quintet in C, of which we only possess the Diabelli piano arrangement - has someone already tried to create such an reconstruction?
Would be very interesting, as i think it would confirm that the Beethoven of opus 135 and the opus 130 finale is creating distance from what we now call his "late style" (specifically regarding opp.132-130-131)
