Delivering a blend of foot stompin' bluegrass and outlaw country seasoned with hillbilly Americana and thrashing metal is Atlantic Beach, Fla. three-piece Grandpa's Cough Medicine. The rugged drawling vocals of fast flat-picking leader Brett Bass (acoustic guitar, dobro) is paired with the twangy higher register harmonies of upright bassist Jon Murphy, their string interplay joined by the five-string finger-picking mastery of Mike "Banjo Boy" Coker. Their songs tell stories of murder, mayhem, love and betrayal, boozin’, crooked cops, doing time, and the blue collar folks who make our little world go ‘round. The cheeky title track off just-released sophomore album, The Murder Chord, is about a boy who discovers heavy metal and slaughters his family (“Soon the songs, they began to change him, relentless drums with blazing double bass / and the twin attack of a rabid thrash guitar with solos that would cause a melted face”), while in “Julianne,” the narrator is a Clyde deserted by his Bonnie and paying for their crimes on death row: “And I wonder if she ever really cared for me at all, or was I nothing more than just a guy to take the fall / I surely wanted her and I became her wanted man, I’d kill and die for my Julianne” (which he does, ultimately). The trio also plays 8th Avenue Pub in Safety Harbor on Friday. Fil Pate joins.
