Mirah Yom Tov Zeitlyn's voice is a thing of wonder—perfectly tuneful yet distinctly personal, able to tackle everything from klezmer to electropop to folk without ever sounding dilettantish. More impressive than her voice, though, is her songwriting, which is full of idiosyncratic humor, home-sewn pillow talk, and a depth of emotion that ranges from geographical longing to deeply internalized anxiety, all expressed with deft poetic language. Mirah is a treasure. With Tender Forever and Fences. (Neumo's, 925 E Pike St, 709-9467. 8 pm, $12, all ages.)
