Rather than admit they missed the boat on the Flatlanders—a fleeting ’70s West Texas combo that included Joe Ely, Butch Hancock, and Jimmie Dale Gilmore—revisionist critics now routinely impart glowing recollections of the band. What’s even more wondrous, though, is that all three Lubbockites are commercially and artistically viable two decades later. The soft-spoken Gilmore is perhaps the most viable of the esteemed triumvirate, and since Elektra resuscitated his flagging career by signing him to its Explorer series, Gilmore’s Hank Sr./Woody Guthrie style and provincial boho charm have attracted the following that he deserves. Opening is up-and-comer Joe Henry at 7:30 p.m. at the Barns of Wolf Trap, 1624 Trap Rd., Vienna. $14. (703) 938-2404. (Dave McKenna)
