On their new LP Get Yourself Outside, Colorado-based quintet Yonder Mountain String Band once again echoes out into the universe its place as not only a pioneering jam-grass act, but also one of the most innovative, intricate groups in the live music scene, something the groundbreaking ensemble has proudly held high for the better part of a quarter-century.

There’s the usual foot-stomping melodies and sorrowful ballads that reside at the core of the Yonder Mountain signature sound, but there’s also a deep, honest sense of renewal and rejuvenation running through the heart of the record.

“The whole thing has always been about the energy and the connection with all of us onstage and everyone out in the audience,” says guitarist Adam Aijala. “And with this iteration of Yonder Mountain, we’re really tapping into that onstage connection once again.”

This “third chapter” of YMSB is one of many facets. Aside from the obvious nature of the new album, it’s a complete restart for the live music industry. Internally, it’s also a fresh start for the group in welcoming its newest member, multi-instrumentalist Nick Piccininni.

It’s also a testament to the life and legacy of Yonder Mountain that three of the founding members — Aijala, Kaufmann and banjoist Dave Johnston — remain at the helm of this American musical institution, something complemented and accelerated in recent years by the fiery fiddle work of Allie Kral, who joined the group in 2015.

Looking back on those early days, the members of Yonder Mountain can’t help but shake their heads in awe — of where it all originated from, and what the live music landscape looked like at that time.

“When we started, we were the only example of what we were trying to do,” Kaufmann notes. “You can see a bluegrass band at a rock festival now. But, there was a time where something like that was incomprehensible.”

And it’s the fearlessness of youth — of being present within the serendipitous whirlwind of artistic collaboration and musical discovery — that remains a thick thread of inspiration and ambition within Yonder Mountain.

“I’ve never doubted for a second that this band wouldn’t work,” Kaufmann says. “That’s a wonderful experience to have known that early on — to not have fear or doubt in the creative experience. And when you think of it, how unlikely of a journey has this been?”

From selling out Red Rocks Amphitheatre at a time when that was unheard of for a string act, to standing at the microphone in front of tens of thousands at festivals like Bonnaroo, Yonder Mountain was the initial spark in an acoustic inferno decades ago that endures headlong into the 21st century — one burning brightly in an ongoing movement that now includes marquee names like Billy Strings, Greensky Bluegrass, and The Infamous Stringdusters.
