Pop Music:

The new Sinatra? Perhaps. A recent guest in the White House situation room? Definitely. Jay-Z is many things to many people, but at this victory-lap arena show, he’ll cement the skill that got him there -- hyper-nuanced flows, effortless lyrical dispatches from the corner and corner office alike, and the gargantuan charisma that’s left him one of the last rap titans standing commercially. Staples Center, 1111 S. Figueroa St., L.A. 7:30 p.m. Fri. $39.50-$129.50. (213) 742-7300.
