thanks a lot! I'll have to listen to your recording later too, but at the moment my connection is so slow, I have to wait for a while.. would be great to read your 185-page paper on this piece by the way!
About the "complex score" - I guess you have to work on the piece from time to time; there are always new markings that you didn't notice the previous time you were studying it. But on the other hand, I feel that most of Bergs markings come naturally.
I learned it over half a year ago and felt I wanted to work on it again and finally play it in concert. The recording was taken from a student concert at a course I went to for Liisa Pohjola (teacher at the Sibelius academy in helsinki). You probably noticed the memory slip near the end - luckily I let my hands keep playing and I eventually found a way to continue..
