Well, I give up. I can't find anything that trashes Jonas' recording. All point out that his interpretations are unusual, one German reviewer going so far as to say that it was "as if hearing it for the first time." You don't get better than that. My heart isn't in this search anyway.
I liked finding the article saying that his new heavier style of singing came from his singing in the shower style, not a precise quote, rather than from what agents and managers had planned for him. Or maybe it was the Zurich Opera that had this plan. His light voice singing is pretty but relatively boring. You can hear this on Cecilia's video of Nina.
If I refer to him as Jonas Buyer, the literal translation of his name, maybe it won't Google.
He aspires to sing Tristan and Otello. About at 45 I would say.
People who hated the camera work on the simulcast of Tristan und Isolde should tell the Met. I didn't necessarily hate it, but it was more interesting than strictly necessary. The enemy for me is always boredom.
Rats! I caught myself listening to Christine Brewer's Isolde just to see. Her voice is bigger than Debbie's but less edgy. I'm not really ready to be seriously interested in Tristan und Isolde.
