The dynamic, virtuosic and ever-evolving acoustic outfit Mountain Heart have never sounded better than on their new release Soul Searching. Incorporating bluegrass, Americana and pop influences, Mountain Heart’s sound is a true hybrid - a surprising achievement for a band previously thought of as a traditional bluegrass band. The quartet shines on the album’s first single “More Than I Am,” with a pulsing piano groove and driving mandolin rhythm providing the framework for Shilling’s soulful vocal. By contrast, “No Complaints” cops the spirit of a New Orleans second line, achieving a cross between New Grass Revival and Little Feat.
