I recently made a beautiful discovery: in 1832 Schumann wrote an unfinished symphony in g-minor of which the first movement - I think - is really great - full of furious power. What do you think of this work? Why did he not finish it? https://youtu.be/6Kvw_xiDL4k?si=md9re4Hay6mu4w7Z
Mariss Jansons recorded it in the late 70s or early 80s. I think he was the first to do so, and I still have the LP.
Since neither Schumann nor the Zwickau symphony can possibly qualify as "Unsung", I'm locking this thread.
