By 19, Markéta Irglová had already won the hearts of indie-musical lovers and an Academy Award for Best Original Song for her work in Once. But since drifting away from her co-star and writing partner, Glen Hansard, after the duo’s second album in 2009, Irglová has spent her time exploring the world and gathering musical traditions, which she incorporates into her solo albums. Her 2011 release, Anar, drew influence from an extended stay in New York City, while last month’s Muna is inspired by her current home in Iceland and the heritage of her Iranian collaborator, Aida Shahghasemi. But while these global sounds tell the stories of where Irglová has been, her sweet, unaffected voice and simple piano remain at the forefront of Muna’s 11 tracks; they call to mind exotic locales but feel as comfortable as a worn-in armchair. Markéta Irglová performs with Rosi Golan at 7:30 p.m. at the Hamilton, 600 14th St. NW. $18–$25. (202) 787-1000. thehamiltondc.com.
