The King's daughter had to clear a few hurdles in her music career. A) Her father is considered (rightly or wrongly) to have invented the genre she's working in. B) Her face looks like eerily a composite photo of Priscilla and Elvis. Freighted with that, what chance do you have to start with a clean slate? It's understandable that her rock 'n' roll skews angry, courting Melissa Etheridge more readily than "Blue Suede Shoes."
