No! Heavens no! Not poorly played! I just meant that it gives this sense of utter hopelessness. Like all is lost, then it tapers off and Bleak comes on and it just grooves (at the beginning). If you're in a fragile emotional state that's the kind of thing that can make you cry.
Yes, it is beautiful, brilliant, and terrible all at the same time. Terrible because it can bring up so much emotion and sometimes that's not a good thing.
A better question would be "How can one piano solo, not to complicated either, have so much feeling?"
