DEX ROMWEBER DUO Siblings Dex and Sara Romweber — the guitarist and drummer of this Chapel Hill duo — have been essential players in the North Carolina independent music scene since the ’80s. Sara played with Winston-Salem pop-rockers Let’s Active, while Dex’s Flat Duo Jets' scorching rockabilly influenced, among others, some guy named Jack White.

With The Dirt Daubers. $8. Sept. 9, 9 p.m. Snug Harbor, 1228 Gordon St. 704-333-9799.
