Grandpa’s Cough Medicine brings its outlaw bluegrass sounds to Hippie Hill for a Saturday set, Aug. 16. The Jacksonville, Fla., three-piece blends some furious banjo pickin’ with humorous, hardcore hillbilly lyrics for a good-time outdoor throwdown. The band says music fans can expect a blend of original music, traditional bluegrass songs and instrumentals, classic country and even some rock ’n’ roll that has been given the bluegrass treatment.
