NPR has described their approach to music as "gorgeous contemporary folk" and "Gillian Welch & David Rawlings-meets-Simon & Garfunkel with a splash of The Everly Brothers", which fairly represents the band's music while also appealing to the intended audience. The band has recorded and released four albums: "Retrospect", "Prologue", "The Ash & Clay" and "Monterey". The forewords to both "Prologue" and "The Ash & Clay" were written by singer-songwriter and producer Joe Henry.
