Born John Michael Dexter Romweber, under the sign of Gemini, the rockabilly-roots musician currently known as Dex got his start in Chapel Hill two-piece Flat Duo Jets. That band, and Romweber specifically, "was and is a huge influence on my music,” Jack White said in the 2006 documentary, Two Headed Cow. Still a fan of the guitar-drum two-piece Romweber now fronts Dex Romweber Duo with sister Sara Romweber (of '80s-era post-punk band Let's Active); the two released Is That You in the Blue? last summer. (White's Third Man Records label re-released The Flat Duo Jets' 1991 LP, Go Go Harlem Baby last year, as well.) The Romweber siblings play Jack of the Wood's Garage Blaster (with The Moodees, Pleasure Chest and Broken Lilacs) on Friday, June 15. 8 p.m., $8. http://jackofthewood.com. Photo by Meg Wachter.
