Seeking mezzo role models

After finding that Stephanie Blythe youtube video, I've decided to start a "mezzo file".  Doesn't have to be opera - e.g., Karen Carpenter moved effortlessly & seamlessly between her head & chest voices, and I've loved Annie Lennox' voice from the first time I heard it.  Denyce Graves is gonna be on that list, Joyce Didonato, at least one local diva - I'm on the hunt! :)
