Frederica von Stade seems so nice it's hard to imagine her being Vitellia; but then again, she could show us a gentler side of the character. She certainly makes a good musical case for one angle I’ve suggested now and then: Vitellia as a hurt little girl.
Gratuitousness Updated: meanwhile, I finally caught up with my indexing. I thought I was way behind, but I didn't post many (any) random clips in 2016, so catching up didn't take long. I think I now have all the aria/duet clips cataloged (clearly I am someone with too much spare time!) The next step is to go back and un-index stuff that's been deleted from YT (or update links). That may take longer!
