Emmylou Harris, Patty Griffin, Shawn Colvin and Buddy Miller -- “Three Girls and Their Buddy” -- offers a night of graceful songs and stories from each of these four country/folk stars’ memorable careers. They’ve all frequently appeared on each other’s albums, so expect a lot of group jams and duets – a definite concert for the memory books. Sunday, May 31, at 8 p.m. Wolf Trap, 1645 Trap Road, Vienna. Tickets are $22 to $42. Call 703-255-1900 or visit www.wolf-trap.org.
