I… don’t actually like opera, with the following exceptions. So my answers are (a) not representative, and (b) damn good, if they got past my “I don’t like opera” filter.
- John Adams, Nixon in China.
- Alban Berg, Wozzeck.
- Wolfgang Mozart, Don Giovanni.
- Richard Strauss, Der Rosenkavalier.
Need a fifth, OK:
- Benjamin Britten, Peter Grimes.
Thirty years ago, but I remember liking it at the time.
EDIT: Strike that. I meant to say
- Philip Glass, Akhnaten.
