I've been recently listening to the below interpretation of Liszt's Hungarian Rhapsody #6 by György Cziffra.
Between 1:40 and 1:50, he improvises a custom cadenza which I couldn't find written out. Would you happen to know what it is or where/how I could obtain the notes? I'd be interested in playing this (I'm currently learning this rhapsody), but it seems too complicated for me to write down by ear.
