Emmylou Harris has released 21 solo albums, won 13 Grammy Awards, and racked up countless collaboration credits with musicians ranging from Gram Parsons and Bob Dylan to Bright Eyes and Ryan Adams. Her voice, smooth and pure with just enough twang and wear to make it honest, has carried her through five decades of making music and into a sixth. Her status as a living legend was solidified when younger musicians started writing songs about her. (First Aid Kit’s “Emmylou” is among the finest.) Harris’ performance in D.C. will be a homecoming of sorts: Harris met her long-time friend and collaborator Rodney Crowell while she was living and playing shows near Dupont Circle in the early ’70s. But don’t come to her show expecting a blast from the past. Harris’ latest albums with Crowell—who penned “Bluebird Wine,” one of her first big hits—bring to mind Gillian Welch and Dave Rawlings, except with a lot more Texas and a bit less Appalachia. It’s a reminder that, when it comes to duets, friendship can be just as powerful a motivator as romantic love. Emmylou Harris performs with Rodney Crowell and Rickie Simpkin at 7:30 p.m. at the Hamilton, 600 14th St. NW. $90–$250. (202) 787-1000. thehamiltondc.com.
