It is hard to think that he could ever sing any better than he is right now. This is all so gorgeous.
The arias from Lohengrin, here in the album Sehnsucht and posted on YouTube, show Jonas Kaufmann singing sotto voce quite a lot of the time. This doesn't really give you an idea of his suitability as a Heldentenor, a Fach that sings big most of the time. Not to worry, he sings big very nicely. I can't wait to hear more.
There's just so much there when he sings. Such a beautiful, intelligent man.
Footnote: I notice the word "Sehnsucht" is missing from the US version. The album has no title.
