Kaki King is everywhere, including the Birchmere on Tuesday

From collaborations with uber-producer Timbaland and other artists such Tegan and Sara and the Foo Fighters, plus contributions to movies such as Into The Wild and August Rush -- not to mention NPR frequently plays snippets of her music between news segments -- lesbian guitar virtuoso Kaki King, with a signature percussive sound, is ubiquitous if still under the radar. Tuesday, March 29, at 7:30 p.m. at 7:30 p.m. The Birchmere, 3701 Mt. Vernon Ave., Alexandria. Tickets are $25. Call 703-549-7500 or visit birchmere.com.
