It essentially means a great catastrophy, but it is actually a bit more complicated than that as it can also denote the anticipation of such an evil.
Thanks for the Pollini posting. It does not suprise me that Pollini, with his bent towards contemporary music, choose to record some of the most dissonant, late Liszt (No Hungarian Rhapsodies, no operatic paraphrases, no galopp chromatique from him...). Too bad he never recorded the TE.
Yes, I can`t exactly imagine Pollini recording the Hungarian Rhapsody no2, but possibly no17(considering that it is a late piece and is very modern and free of vulgarity).
I am very glad that Pollini decided to record late Liszt, since so few plays it
It would of course be amazing if he decided to redord the complete TE`s. You can find a vid of him playing no10 on youtube:
It is the most exiting and technicly impressive recording of this piece. But for some reason, most people doesn`t like it

And could you explaine the meaning of the piece a bit further?
