A freewheelin’, trashgrassin’, folk tornado, the Whiskey Shivers take traditional instrumentation, soak it in gasoline and send it into outer space. Breakneck speeds, killer grooves and impeccable musicianship: it’s enough to make Bill Monroe himself do a double-take as he spins in his grave. With upright bass, fiddle, washboard, banjo, guitar, and reasonably priced merchandise, Whiskey Shivers adds a fine layer of grit on top of the hard-driving rhythms of traditional bluegrass. They’ve been called everything from “trashgrass” to “hardcore roots” to “crazy-assed redneck music” — whatever the words, the meaning is the same: Whiskey Shivers brings the house down.
