What do you appreciate about Tarja, and where do you see room for improvement?

I appreciate her: her tenacity, her voice, her willingness to try new things and genres, and not confining herself to one box. And last but not least, she is a damn beautiful woman.

Areas for improvement: the willingness to slow down. There’s a risk of burnout. I love her voice, but I think she doesn’t let it rest, and there are performances I’d imagine being sung differently. I love her freedom. But I think that sometimes she could use vocal guidance—someone to say, "Not like that." And then she does something that takes my breath away.
