Constantine has an answer & I think a very well thought out response to Kara "I don't know who you are" DioGuardi.
Constantine Maroulis, guest-blogging for the L.A. Times calls her "an interesting rock-opera sort of artist." There you go, she's "rock-opera."
Constantine also said, "I think there are a couple producers out there who are thinking, "Mmmm, I wanna get my hands on her!" because she really has a freakishly interesting voice." There you go, that's called "blank slate."
