Grassy Creek Vineyard - Sunday Music Series by the Fire featuring The Brown Mountain Lightning Bugs! The Brown Mountain Lightning Bugs are folk(ish) duo from Winston-Salem with a passion for bringing original music to audiences in North Carolina and beyond. Kendra and Zack began gig-swapping as solo artists in 2014, and decided to tie the knot in the fall of 2015. Combing their unique backgrounds that range from classic rock to classical guitar, they create a blend of original music with deep roots in the past and contemporary twist here and there.
