Norah Jones at Shepherd's Bush Empire, London

At 23, Norah Jones is both old beyond her years and curiously insecure in front of an audience, even such a plainly partisan one as this. Maybe it was because she found herself perched uncomfortably on a drum stool instead of her usual pair of telephone directories ("I'm kinda short," she explained). Or maybe the reserved and reverent nature of the crowd put her off, as if they were sitting back and waiting to be impressed instead of empowering her with waves of sympathetic energy. Americans probably do that kind of thing better.
