It's the bouncers' night off at the Savvis Center this Friday when Norah Jonesbrings her polite, gentle jazz to town. Chaos, however, ought to reign over at the Rocket Bar both Thursday and Friday: Captured! By Robots is pulling a two-night stand. With one human and a bunch of robots (for real) rocking out and trying to take over the world, it's a spectacle of the highest order.
