My personal favourite conductor, and perhaps the last great Wagnerian. Not my favourite composer by a long chalk - that would be Purcell - but stuff from the romantic era tends to be a lot more "immediately" powerful, especially to the casual listener.
You don't need a knowledge of musical form and convention, historical context, or even the story behind this scene to enjoy it (unlike a lot of baroque stuff).
Such knowledge will of course elevate one's appreciation and enhance overall enjoyment, however.
