I found this gem of a duet of two talented South Koreans (one is American Korean):
The conductor can really sing!!! However, I am more wowed by the lady, American-born Rose Jang, daughter of a National Seoul University graduated who then pursued his doctorate at Princeton University and finally settled down with his family in the USA. Quote from her biography:
"Princeton-born Rose Jang is an acclaimed award-winning Korean-American pop opera artist who is well-known for singing operatic arias, musical and classic pop songs."
A very private person online, I cannot get much personal information in English about American born Rose Jang, but I gathered if she was 30 in 2009, (as quoted in one news report), then she must have been born in 1979. That's all I gathered. The rest are polished background info easily found online.
I love her voice and her whole persona. I noted that in 2011 in an interview in Korea (most recent video I could find online) - she has put on quite a bit of weight, more like water retention on her face and arms. Her voice is still splendid nonetheless.
The other classical cross-over singer I like is Hayley Westenra. She's in her 20s now and has been singing since she was a little girl, then blossomed into a wonderful teen with a big voice.
I hope Rose Jang and the New Zealander Hayley can perform a duet some day, or maybe Rose may attempt a cover of Nella Fantasia or the English version with lyrics penned by Hayley herself - Whispers in a Dream as embedded below:
It is only viewable on desktop/laptop but not on mobile.
There are many more talented ladies (and even little girls) in this genre. Usually they dislike it when you refer to their genre as poppera or popera (pop+opera), so classical cross-over it is!
If you haven't checked out this genre before, search for these two names on youtube, and there are scores of many more like Sarah Brightman, Katherine Jenkins, Celtic Women, and oh, the ever so adorable Jackie Evancho (- there are many more you just need to discover them as it will do no good to list them out one by one!
