Mozart is the most easily appreciated of classical composers, and a good place to start. If you jump into Mahler, or even some Beethoven, you might drown.
I used to enjoy some radio programs where the music, often several renditions by different performers, was accompanied by a lecture about the music, and comparing the different interpretations.
