Colorado's Yonder Mountain String Band has taken a new, bolder form in the last two years. "New Yonder" is now a five-piece jam-grass band after Jeff Austin departed the group in 2014 — the band has since added Allie Kral (fiddle) and Jacob Joliff (mandolin). The band has eased its hesitant, long-time fans into the transition with new originals — YMSB's fifth album "Love. Ain't Love" was released last June — and by covering audience favorites by The Grateful Dead, Talking Heads, and even Dolly Parton. YMSB is pushing forward with tact and a drive to expand its sound.
