Irglova is a calmer, more studied performer. At the 9:30 Club on Monday night, on her first tour as a solo artist, the 23-year-old Oscar-winner reaffirmed the beauty of her singing while demonstrating that the new songs she’s written on her own don’t have the transcendent power of those she and Hansard write together.
Things picked up when she introduced the most prominent member of her three-piece band, Iranian singer and percussionist Aida Shahghasemi, who played a large, hand-held drum called a daf. After what was surely the most epic drum solo in delicate, interior, piano-based-indie-folk history, the two women sang songs in their native tongues. Irglova traded her keyboard for a guitar to close the set with “I Have Loved You Wrong.”
