Girlyman, a sweet and sensitive queer quartet of three girls and a boy creates its own soaring three-part harmony in the acoustic-leaning folk-pop manner of the Indigo Girls and Paul Simon. Last year's live album, Somewhere Different Now , captures the banter that makes the trio an engaging presence on stage. Their music is just about flawless. Friday, Nov. 19, at 8 p.m. The Barns at Wolf Trap, 1645 Trap Road, Vienna. Tickets are $20. Call 703-255-1900 or visit wolf-trap.org.
