Bugs Bunny on Broadway

I went to to see Bugs Bunny on Broadway -sponsored by the Philaharmonic- last night and it was great. I really enjoyed myself. I am trying to find what genre of classical music I like and how to understand a piece of music. I am a newbie at this. I want to understand the point of that piece of music. There is so much feeling and passion behind it. Anyone have any suggestons?
