This is an enormously moving piece.
There's a piano solo version (Public domain) at IMSLP.

The third movement is at the page marked 103 in the score.
I have been working on Brahms 2nd piano concerto, mostly the second and third movements. These can actually be played without orchestral accompaniment. There is a "music minus one" out there but the orchestra is synthesized and I am wary of it. Maybe some day (when I get my IRA distribution) FYI, the third movement is about as sublime as the piece in the OP. (starts with the lovely violin solo)
I got a bug to try the piano reduction of the 1st symphony. (2nd. and 3rd. movements)
In the background are the andante moderato from the 4th symphony
And the well-known 4th movement (passacaglia)
Just learned that the passacaglia is based on Bach's Nach dir, Herr, verlanget mich, BWV 150
Never a dull moment!

THANKS FOR MAKING THIS A MUSICAL EVENING FOR ME.
Cleaning up comes later tomorrow. 
As if I needed an excuse.
