5. Casey James. It was another great call from mentor Adam, pointing out that Casey's performances often lack an arc. It's almost always decent-to-good, but there's never enough dynamics. Casey (right, photo by Fox) should have listened closer, as his rendition of "Lawdy Miss Clawdy" was serviceable, but predictably boring. Last week proved Casey was more than just long, blond hair, but this week was a clear step backwards. If Casey is still around at the end, I'm going to be beyond tired of his bluesy, ax-man shtick.
