Emmylou Harris performed Joan Baez-style folk music regularly in D.C. clubs in the late 1960s. But in 1971, when she first duetted with country-rock singer Gram Parsons, he encouraged her to sing more classic honky-tonk country. Fifty years later, Harris’ soprano still has a twangy pureness whether she’s singing folk, country, gospel, or rock-rooted material. While Harris sometimes writes her own songs, she is better known for her astute skill in making other people’s songs her own. Harris had her breakthrough commercial moments when she collaborated with Dolly Parton and Linda Ronstadt, including 1987’s Trio, which topped the country chart and reached the pop album top 10. Since the 1970s, Harris has covered the songs of Steve Earle; they’ve done gigs and activist work together, and this fall will be bringing “The Lantern Tour: A Concert for Migrant & Refugee Families” to the area. They’ll will be joined by Amy Helm, Larry Campbell, and Teresa Williams, plus Thao Nguyen of Thao & the Get Down Stay Down. Proceeds benefit the Women’s Refugee Commission, which works to protect the rights and lives of women and children fleeing danger and crisis. Oct. 28 at Capital One Hall, Tysons. $72.50–$202.50.
