October 19. Liv Carrow (vocals, guitar) and Sasha Pearl (vocals, banjo) had each already been playing and recording for years before they met at a 2011 harvest celebration. During the first of many parlor sessions to come, they discovered their dreamy voices blended like gossamer corn silk, and with Emily Willis (violin, mandolin), the pair formed folk threesome Pocatello. This evening at the Spotty Dog Books & Ale trumpets the trio’s first record, a seven-inch single produced and released by local rock god Tommy Stinson (Replacements, Guns ’N Roses, Soul Asylum). Like-minded roots unit the Happy Jawbone Family Band opens. (Sasha Pearl plays solo October 10; Janet Wygal’s new band Wygalator woos you October 20.) 8pm. $5. Hudson.
