I bought the CD from which this is taken a while back. I like the recording, but the first time I heard this track, which is Zerlina’s aria ‘vedrai, carino’ from Don Giovanni my reaction to the concept of Kasarova as Zerlina was somewhere between absolutely not and I would like to see this attempted. I don’t know why I found it so odd. I think it’s because I associate her with trouser roles and this would be very different. (And also, she’s a mezzo, and it’s a soprano role — but this often doesn’t make as much difference as you’d think.) But mainly it is because I have seen DVDs of her performing and her stage presence can be downright peculiar.
But there is “bizarre but it ultimately works” and “you think it would work just fine but no one ever wants to talk about it ever again.” I’m still not sure which this concept would be, but since it’s never going to happen it’s kind of a moot point.
