What is Karen Carpenter’s best vocal performance?

[Villavic]

I think this is the wrong poll. I mean, I feel it's impossible to choose a best performance. There are so many. So, maybe it would be easier to find a bad performance. Not that easy, of course, since she was a great performer. But probably there is one, hidden among so many great works.

I read her solo album was not good. Critics mentioned it was recorded with a wrong vocal range for Karen. So maybe the worst performance could be within that album, though I've never listened it.
