I love to hear a few singers at a time, comparing each other like this.
Sitting in front of my screen, I can review all these girls at once just by clicking.
I am no expert in this business but, regardless, I have my own feeling and opinion.
 (May I be brave and stupid enough to say that?)

Maria Callas in the main webpage: I think this is probably the best one to listen to.
It had to be her performance at her prime time.
I don't get tired no matter how many times I hear. Is this so-called Bel canto?

Anna Netrebko: One of the two bests in this group.
She's very similar to Maria Callas in the main webpage above.
I would dare to say this is Bel Canto (nothing technical, just beautiful singing).

Maria Callas: I think this one was when she slimmed down (after weight loss).
Her voice seems to be broken here and there. It's not like the singing in the main webpage.
I guess she could have been over the hill by this time. Her heydays were gone.
Why did she sacrifice her voice for the external appearance?

Renata Tebaldi: She was supposed to be a competitor to Maria Callas
but, to me, she isn't comparable at all to Maria Callas at her prime.
Somewhat careless in her singing. She seems to be much older in the picture.
Could she have been much better in her younger days?

Montserrat Caball: It seems that she lacks continuity. Not much fun to listen to her.
Obesity may be a good thing for voice but too much of it may not be good.

Sumi Jo: I heard her a lot but this time I am somewhat disappointed here
but I think it could be a bad recording.

Youngok Shin: She's another best in this group. Outstanding technique and expressions.
Her voice is wonderful. Long time ago, I think I composed a webpage with her singings.

WM 의 견해에 전적으로 동의 합니다.

Anna Netrebko 는 Maria Callas 이후 최고의 오페라 가수 (?) 라고
저는 생각 합니다. 아마 상업적 가치로 따지자면 그렇겠지요.

조 수미 는 음 용량이 좀 부족 하다고 늘 생각 해왔는데 그런가요?
홍 혜경이 Met 무대에서 큰 성공을 거두는 것을 보고는
자기는 필적 할수 없으니까  귀국해서
한국의 디바 노릇을 혼자 하고 있다는 평들도 있더군요.
신 영옥씨 노래는 자주 들어볼 기회가 없어서 잘 모르겠고,
Tebaldi  와 Caball 은 옛날 가수 들이라 역시 잘 모르 겠습니다.

위에 댓글로 New Divas 올렸습니다.

In some of Sumi Jo's recordings, she seemed to have a good volume (not here though).
I heard her in Denver a few years ago and her voice did fill the big concert hall.
That's why I am thinking that the recording was bad.
Unless we hear the singer in person, it may be all up to the recording !!
As you know, Sumi Jo is an old woman (born 1962).
(though it's ridiculous for me to say that she's old !!)
Then Youngok Shin is 1961.

In the world of glamor, it's always....
興亡이 有數하니 滿月臺도 秋草 로다.
I am glad I chose to be a medical doctor. Nothing fancy but it lasts.

한때는  여러번 석주와 이곳 데트로이트에 이웃인 카나다 윈져에서
기차타고 토론토가서 그곳 쇼랑 오페라를 관람한적이 있었는데
신영옥이 디바로 나오는 Lucia di Lammermoor를 보게되어
완전히 매혹된 청중들을 보고 한국인으로서의 긍지를 느꼈지요.
10 몇년전 일같습니다.

조수미씨는 이곳 데트로잇을 10몇년전에 방문했었는데
미시간 의사회에서 내동네 컨트리클럽에 초청해서 저녁식사랑
같이하고 우리들을 위해 노래까지해줬는데
나와 석주는 바로 옆에앉게되어 그분의 호탈하고 쾌활한 성격도 접할수가 있었읍니다.
자기가 서른 몇살인데 남편감을 골라달라고 까지 부탁을 받기도 했지요.

오페라를 별로 즐기지 않던 나를 석주, 집사람이 나를 많이 계몽시켜서 링컨센터 메트로포리탄 오페라 관람도 가보고,
이제는 조금  즐기는 편이지만, 신영옥, 조수미, 홍혜경은  우리 한국이 낳은 국가적인 보배들이라는것은
잘 알게되어 다시한번 새삼 강조하고 싶은 마음입니다.
