She has a great voice. And I dig the sound. The problem though, is for all these "new classic rock" bands is they kind of all sound the same, because they kind of don't get it. Throw some classic sounding guitars on top of an organ (or more likely, a synth) and call it a day!
That song sounds very, very similiar to Woman by Wolfmother.
It's also kind of why bands like this usually don't gain much traction. Everything sounds the same.
