The power of one woman with a mic and a guitar is a force to be reckoned with. Now double that. Thao Nguyen (of The Get Down Stay Down) and singer-songwriter Mirah do just that on their debut, adding tUnE-yArDs' Merrill Garbus as producer for a trifecta of Bay Area female fierceness. The quirkier spots point to Garbus, like the clickety-clackety punch of opener "Eleven"; her eccentric touches balance beautifully with Thao's subtle grit and Mirah's softer inclinations. Whether they try on waltzing folk, sun-kissed acoustic, loopy pop or big-band jazz, it all fits like a glove.
