Born in Deadwood, S.D., and raised without electricity or running water, Cris Williamson knows something about being a voice in the wilderness. A co-founder of the influential indie label Olivia Records in the ’70s—and a lesbian singer-songwriter who’s seen her ilk rise and fall in fashion—Williamson combines diligence, zeal, and a clarion voice to get her messages across. And though she’s said, “I often wish for more media access so that the music could reach and help more people than it can by being hand-carried,” she continues her musical crusade with performing, teaching, and running her Wolf Moon label—all without much mainstream focus. Nonetheless, her 1974 album, The Changer and the Changed, sold more than 60,000 copies in its first year of release, and friends in the know tell me it’s still bestowed upon fresh-from-the-closet women like a welcome-wagon gift from their lesbian sisters. Williamson plays with Holly Near at 7:30 p.m. at the Birchmere, 3701 Mount Vernon Ave., Alexandria. $22.50. (703) 549-7500. (Pamela Murray Winters)
