Brooklyn-based singer-songwriter Mirah has been making thoughtfully restrained confessional music that straddles the line between folk and pop for more than a decade. On her early work, such as 2000’s You Think It’s Like This, But Really It’s Like This, her voice is light and breathy, accompanied by minimal instrumentation — the total effect is equal parts beautiful and piercing. Since then, she has experimented with more orchestral, brass, and electronic sounds, but lyrically, her music is as direct and affecting as ever. Mirah hasn’t released a solo album since 2009, but her 2011 collaborative album with Thao Nguyen (of Thao & the Get Down Stay Down) — which was produced by Merrill Garbus of tUnE-yArDs — was spectacular. She’ll perform at The New Parish (579 18th St., Oakland) on Friday, in advance of the release of her new album, Changing Light, which comes out May 13.
