Looking back over the past 25 years of rootsy, string-based music, the impact of Leftover Salmon is impossible to deny. Formed in Boulder at the end of 1989, the Colorado slamgrass pioneers took their form of aggressive bluegrass to rock and roll bars at a time when it wasn't so common, helping Leftover Salmon become a pillar of the jam band scene and unwitting architects of the jam grass genre. Today, Leftover Salmon is: Vince Herman (vocals, acoustic guitar, washboard); Drew Emmitt (vocals, acoustic and electric mandolin, electric guitar, fiddle); Andy Thorn (vocals, acoustic and electric banjo); Greg Garrison (vocals, acoustic and electric bass); and Alwyn Robinson (drums). NPR’s Mountain Stage heralded Colorado’s Leftover Salmon as “one of the most beloved acts on America's summer-festival circuit.” After changes and a hiatus, Leftover Salmon is officially back. “The time is right for this band to come back on a lot of levels” says Drew Emmitt. “It’s taken us a little while, but I think we’re finally there."
