Is There An Opera You Changed Your MInd About?

I saw Rigoletto 20 years ago before I was into men's voices and was sort of ho hum about it even though the singers were fine. I always liked Caro Nome but that was about it. I was given a lp boxed set a year ago and it sort of languished at the back of the pile until I got my new turntable and decided to try it. I am glad I waited as doing the contests has made me appreciate male voices so much more. Now I really love Rigoletto ( I have the one with the gorgeous voiced Milnes, Pavarotti and Sutherland). Not just the singing but the orchestration is so very beautiful. The story doesn't appeal to me so much but the music is so gorgeous it definitely has become a favorite of mine. The weaving over the voices in the first scene is exquisite and exciting and that duet between father and daughter is so gloriously beautiful! It also helped a lot that I have started following along with a libretto of late when I listened to music since I have them with lp sets. Have you changed your mind about an opera over the years?
