Is there anybody in the District who’s aged better than Chuck Brown? He got his start 40-some years ago, at a time when the local music scene wasn’t the easiest place to break out of. There were plenty of clubs back then—just very few labels and a whole lot of schemers. But Brown kept at it, wringing blues from his guitar in backyards for beer and barbecue. Graduating from the barbecue circuit to soul covers to inventing that go-go beat should have been enough. Now add a few more decades of steady gigs, hard playing, some tragedy, and contending with being called a legend everywhere you go. But as he gears up for tonight’s 73rd-birthday tribute, Brown remains the coolest guy gigging on any area stage. And since making Fenty look soulful at his inaugural ball, Brown can add miracle worker to his list of honorifics. Wind us up, Chuck. BROWN PERFORMS WITH CHOPTEETH AT 8 P.M. AT THE 9:30 CLUB, 815 V ST. NW. $25. (202) 265-0930.
