In just a few short years, Lyons-based Spring Creek Bluegrass Band has become one of the most popular traditional bluegrass groups in Colorado. While the pairing of the words “popular” and “traditional” may seem at odds–especially considering the success of  New Grass bands that incorporate elements of rock, jazz, and electronic music–Spring Creek conveys infectious, youthful exuberance without straying from bluegrass’ roots. And it plays those roots without coming across like a historical reenactment.

Banjoist Chris Elliott, bassist and fiddler Jessica Smith, guitarist Taylor Sims, and mandolin player Alex Johnstone share vocal duties, pick their instruments with impressive skill, and sing with a whole lot of soul. When the group plays Swallow Hill tonight, it’ll perform tracks from its new album, Way Up on a Mountain.

Spring Creek’s minty fresh LP was released by Rebel Records, a long-standing, Virginia-based bluegrass label that delivers the music of legends like Ralph Stanley. This is a major accomplishment for a Colorado bluegrass band. As the Rebel website points out, Spring Creek is the first band “west of the Mississippi” to be on the storied label.

The Blue Maddies, a five-piece Longmont group featuring KC Groves (founding member of the all-female string band Uncle Earl), will open the show.
