What was the first concerto you leared? How old were you? Did you perform it by yourself, with 2nd piano orchestral reduction, or with an orchestra (which one)? ect... I am 14 years old and sadly haven't tackled a piano concerto, but I have plenty of time.
You should definately play 1st movement before you play 3rd movement of Griegs Am concerto. Believe me! I'm norwegian. I know that concerto better than most others.
Another thing...where do you people get your orchestras? I've never had access to a local orchestra, I don't really think they exist..
