The female bonding continues. If the male-female ratio at the opening weekend of “Sex and the City” was somewhere in the neighborhood of 1:200, expect similar numbers at Tuesday's concert. (Maybe there'll be a demographic shift from the coutured-up to the hemped-out. Maybe I'll get sucker punched for pigeonholing.) Of all the acts to rise out of the late '80s folk revival — 10,000 Maniacs, Tracy Chapman, Suzanne Vega — the Indigo Girls have managed to stay relevant the longest. Now more than 20 years into their career, Emily Saliers and Amy Ray still thrive off a pretty simple recipe: two guitars, harmony, literate lyrics and diverse influences (Saliers comes from the Joni Mitchell tradition; Ray draws from more abrasive influences, like the Jam and Husker Du). The duo's latest, 2006's “Despite Our Difference,” finds them crafting some of their strongest and most raucous material in years. Up-and-coming folky Brandi Carlile, whose latest album, “The Story,” was produced by T. Bone Burnett, opens the concert.
