I dare you to learn the third movement of Moonlight Sonata note for note. I have a tab transcribed for guitar as right hand and five string bass as left hand, but I don' think I'm even going to bother.

The best way to get to play like Mozart is to sit with some of his scores and play the parts on the guitar. Soon you'll start picking up on how he writes his pieces and you may even start cracking out random ideas in the same style. And if you really want to get close, then try to minimise 'metal-ising' it. You need to observe how the melodies move and where he goes with them. Of course, you'll need to learn a bit of theory, because the Classical guys knew massive amounts of theory.
