From what I've seen of Eden, as somebody said, she has her off and on performances. When she is on though, she is ON.
I like to say that she has an Eddie Bauer voice--virtually indestructible. Have you heard what she sounded like in the last performance of Brooklyn (Once Upon A Time)? Absolutely AWFUL! Sounded like she had lost her voice completely--but she came back to Wicked later, and sounded AMAZING.
She's like a female Steven Tyler.
