Where should I start with Mozart?

I am normally more of a metallist… however I am told he is very good, and also I guess there is a lot to be learnt from classical music. I just don’t really know where to go first: I like things in minor keys best as a rule, and am interested in stuff with ze piano (for educational purposes), because it’s what I play, but I love all the ol’ strings as well…
Thankyou =)
