Rosanne Cash, a native of Southern California, has lived in New York for the last 22 years. But the South has always held special meaning for her. Born in Memphis, Cash recently traveled the southern states and spent time in Arkansas helping to restore the boyhood home of her father, Johnny Cash. For her three-night residency at the Library of Congress, “The Long Way Home: Songs of Travel and Longing,” she will preview her upcoming album The River and the Thread, hosting a round robin and talking with U.S. Poet Laureate Natasha Trethewey. Expect Cash to deploy her subtle twang and Americana accompaniment (led by husband John Leventhal) to lend support to her lyrics about the part of the country where Emmett Till was killed—and where country music and blues flourished.
