I just came across this thread and since I worked her stage @Palooza thought I'de chime in. She's total crap on stage, no performanship, her backing vocals should have been center stage w/ their energy and vibrato.
My girl likes her stuff so I gave it a chance and even taped it for her but what a waste of tape. She comes off much better on CD but I'm not that interested in all the covers, a faux diva. While "Rehab" is likable she definitely needs to try harder in the originality dept. I'de rather listen to Annie Lennox Doo Wop or even Natalie Cole, both who I have seen and have excellent stage presence. Plus, Annie & Natalie put alot of production value in their recordings, reference vocal stuff when auditioning Hi_Fi gear.
BTW, the cameras caught her bitching out her boyfriend backstage. He tried to calm her down but anyone there could easily tell she was like a deer in the headlights behind the mic. Clearly one of the worst show on the Bud Light Stage - EVER!
