A few weeks ago while driving to work for an afternoon/evening shift I happened upon the ABC Classics radio station doing their countdown of Australia’s favorite 100 opera moments, and got kind of hooked.
(as an aside if you want to (re-) listen to it you can do so at http://www.abc.net.au/classic/classic100/listen.htm)
Subsequently I went out and bought the 8 CD Boxed set of the countdown, and have been gradually listening my way through bits and pieces of it. It is both quite nice music (by and large it seems to miss out on the harsh screeching soprano moments that I usually most dislike in opera) and makes me feel almost cultured (or somethings).
