Brooklyn-based indie folk duo Hearth consists of Sara Horton and Melanie Wiggins, who sing and play their quirky, soulful songs about everything from the vagaries of love in the time of frat-bros and nice-guys to inequality and immigration reform - all delivered with an Indigo Girls meets Simon & Garfunkel meets Kimya Dawson meets something-you-haven't-quite-heard-yet sound.
