Schubert's 10th was left unfinished around 1828.  All that seems to remain
are sketches.  There are at least two recordings of the sketches on CD.

1) Rice 8006 w/ Bartholomee conducting the Liege Philharmonic.

2) Hyperion 67000 w/ Mackerras conducting the Scottish Chamber Orchestra.
   It includes other unfinished Symphonies.

Unfortunately, I have heard neither, but I hope that is of help.
