I have played his 2nd Symphony. It was marvalous, seriously.
The first two movements really demostrates his unique and fatastic way of using the sonata form, especially in such a late romantic stage, it's great to see composers being faithful to this form. I would say the first movement is best in terms of orchestration, 2nd the stormiest, 3rd the most exciting, and 4th the grand finale. Try listening to that.
