Perhaps this is really two different topics, but somehow I doubt two independent threads would generate much discussion.
Anyway, non-opera, non-opperatta, non-lieder recordings. And non-West Side Story.
I'm willing to bet these are nobody's favourite recording by any opera/lieder singer, even if you happen to like some of these records. And if it weren't for boxed sets repackaging back catalogues, I certainly wouldn't have as many as I do.
That said (and feel free to defend the opposite stance), any favourites among them?
