Last weekend, a number of truly talented performers descended on the High Sierra Music Festival last weekend, bringing great jams from a diverse spectrum of artists. Among those musicians were the talented folks of Greensky Bluegrass, who not only played a set on the main stage, but also let loose for an extraordinary late night set.Thanks to Must Have Media, we have our first glimpse into the band’s late night jamboree. The group opened their set with their fan-favorite tune, “Don’t Lie,” before looping into a cover of Prince’s “1999,” only to bring it back into “Don’t Lie.” What a jam! Watch the footage below.Next up for GSBG is a performance at the Ryman Auditorium in Nashville, TN scheduled for tomorrow, July 7th. Don’t miss out!
