Tchaikovsky symphony no. 6

This is just one part of Tchaikovsky's final symphony,
Pathétique Adagio-Allegro non troppo which was supposed to run up to a full 17.36min, a better display would be from Chicago Symphony Orchestra - Sir Georg Solti.
Its filled with dramatic expression of pursuit,darkness and death in one moment and passionate heartwarming sensation the next.
Simply Overwhelming.

To add on, this piece actually contains Tchaikovsky's relation to homosexuality.
I wonder what story he has to say to make such a strong piece..
