Thanks for sharing your experience. I've sat in all parts of Chicago's Symphony Center for various concerts and to me, every section has its particular virtues.
Listening to and attending live classical music concerts may not be as immediately accessible as other forms of music, but go to a few, develop your own style of listening to and experiencing the music (and this is critical -- there's no one "right" way to experience and listen to classical music), and you will be rewarded for a lifetime.
It's also not just Bach and Beethoven and Mozart -- "classical" music encompasses centuries of traditions (baroque, classical, romantic, modern, might be the broadest categories), and it's very okay to enjoy a particular era or composer and not others. But, it's a whole universe to explore and find out what speaks to you.
Lastly, the level of musicianship and the level of complexity in the music at a top tier classical concert is almost unimaginable, whether it's an orchestral concert, small ensemble, or a solo or duo.
So, thank you for sharing this and hopefully this will help spread the word that there is amazing and vital stuff music being created and performed in "classical" circles.
