Hey AJ... Not a bad idea... I could probably do it note for note, however with recording like these, it comes down to how well they were recorded.
I was listening to a version of the Moszkowski Piano Concerto one (3rd movement), and loved it. It was only two years later that I listened to a different version and realised that there was a harp in it, because the original recording didn't record that well.
That complicates things, and then of course, at the same time - I don't know how to notate for a lot of other instruments. Notes I can do, articulation? Not to great at that - you're sul ponticellos etc and other instrumental techniques, I'm not too familiar with.
I am however very comfortable with the piano, because I like trying to combine those instrumental sounds into what the two hands can do in front of a keyboard.
