hot bluegrass, traditional and modern, 9 p.m.
The guys in the Hackensaw Boys met at an Old Crow Medicine Show concert in Charlottesville, Va., and came together with the intention of merging punk rock vivacity and old-timey Appalachian string music. That was almost 14 years ago, and only guitarist David Sickman remains from the original lineup, but the attitude’s the same. And that means propositioning sorority girls while the band imitates “Dueling Banjos” in the “Parking Lot Song,” upturning our existence in the gothic “Box of Pine,” and cracking open a lively hootenanny for “Radio.” As with their Virginia chums Old Crow, the Boys’ studio albums only capture a fraction of the band’s chemistry and live intensity. Like a revival meeting, the spirit’s all in the moment, so catch them on stage if you can. —Chris Parker FRIDAY
