Where would Nico be without his copy, paste and transpose button?
Listening through, the first one - the Sonanta. Who are you and what have you done with Nico?! Only kidding: well, that was something new. Extreme difficulty as always. Am never going to be able to play that. So much for disliking atonalism
The duet was more Ã* la style de Nico. Of course, incredibly hard for both pianos. You're going to become the Paganinni of pianos - that only the best can play while the rest of us

grumble and groan ... He he, nah, that was typically Nico.
Loved the endings!
