Rachmaninov: Piano Concerto No.3

1. how you come across to it:
I think everyone is familiar to this classics, and recently I'm trapped into this piece deeply, it simply shows all the possible capacity of a piano (from massive to delicate, heroic to intimate) in the style of Romanticism, Rachmaninov makes a perfect marriage of a piano and an orchestra (from the huge forces of the last movement ending to the chamber dialogues just after the cadenza of the 1st movement).
2. why this piece?
Apart from Classic Horowitz
we can have Bronfman
3. (and...)
Andsnes (documentary)

P.S. Ashkenazy is better for score-study listening only ...
