first off, you are a brave person to tackle this, and a talented one i'm sure.

I really love this piece, I don't care if its been overly hyped, but I really like it, in fact i'm listening to it now. Quickly learning it? hmm, i don't know, i don't think its one of those pieces that you could learn quickly through the difficult bits, i suppose it is a patience piece, but what can I say about anything that needs alot of techinical work except to say practice slowly, and that in itself takes alot of time. Perhaps listening to the recording and playing with it when you've got it to a certain level. Sorry dude i'm not much of help. I'm going to start tackling it too soon, although i don't think i'll get very far :p
