Diane Birch

Diane Birch is the daughter of a preacher man and the product of a nomadic childhood, so it’s only logical that she’s endowed with soul-soaked pipes and a sound rooted everyplace and nowhere. Her latest, 2013's Speak a Little Louder, presents a more expansive, modern palette. (One spin of “Unfucked,” a delirious bit of blunt-force sanctification, and you'll be hooked.) Here, Birch turns up at the Rubin's unplugged series, Naked Soul.
