Where should I start with Scott Walker?

OK, OK, I get it. I've read of his greatness enough times now, and in comparison to other artists I love (Mark Hollis and David Sylvian, primarily, but also Momus and anyone else who's done Jacques Brel) that the time has come: I'm ready for Scott Walker. The obvious starting point, as far as I can tell, is the compilation 5 Easy Pieces, but I prefer to get to know an artist album by album rather than through an anthology. Chances are I won't enjoy his early works as much as the later ones. So, random Walker fan who fond your way to this blog, which is Scott Walker's best album?
