And then there were seven ... members of Sweet Honey in the Rock. Following the departure of Bernice Johnson Reagon, founder and member for 31 years, the gospel, civil rights, jazz and a capella group added two new members. Its Feb. 18 performance marks the return (after a 27-year leave from the group pursing other interests) of Louise Robinson and the Atlanta debut for new member Arnae. The concert, an annual event for Sweet Honey, benefits the Fund for Southern Communities, which supports small community organizations working for civil rights and other social change issues. $25. 7 p.m. Sisters Chapel, 350 Spelman Lane. 404-371-8404. www.fundforsouth.org/sweet_honey.htm.
