 If you go to one concert this week, make it: Saturday night when the surviving members of Zapp visit Fort Dupont park. It promises to be totally free and deeply funky.

And if you stay up late to watch one artist on television, make it: The very-beloved Stevie Nicks when she visits Leno on Thursday. If you like what you hear, she’s at Jiffy Lube Live on Sept. 3.
