You won’t find many country-music double-bills these days whose kitsch quotient is lower than that of Trisha Yearwood and Lee Roy Parnell. Yearwood has cast off her glamour-girl image and taken her place—along with Mary Chapin Carpenter and Kathy Mattea—among Music City’s booming population of Strong Women. Even so, Yearwood’s still capable of putting seriousness aside and belting outbouncy, mindless gems like “XXX’s and OOO’s” now and then. And while country fans have embraced his theft of ’70s soft-rock stylings (“On the Road”), Parnell’s slide-guitar work has made him a sought-after session man, even among C&W traditionalists. At 8:30 p.m. at Wolf Trap’s Filene Center, 1625 Trap Rd., Vienna. $14-24. (703) 255-1860. (Dave McKenna)
