Simon you are an amazing musician don't go with crap like prok 5. Do somethinmg that people will like, such as rach pag. When you've won and your name is famous, then start looking at the strange stuff. Because lets be honest, prok 5 is bad, everyone admits it, so is a lot of this stuff. It doesn't have that thing about it. People want to hear stuff like rach concerto's played well, and nt many people do it, and I am convinced that you will do a great and unique job. Trust me, don't play totantanz, it's not you, your to sensible for crap like that. And you have the technique for it, so you'll be proving nothing. An audience these days see's far to much bang bang, so don't play liszt.
