this isn't classic or anything, but this soundtrack is the only one i can think of that i've ever listened to outside of the game. jessica curry's OST for amnesia: a machine for pigs. its written to be period appropriate, so it has a classical sort of feel to it. even minus the context of the game, i feel like it is just really great music.
