Charlottesville's Hackensaw Boys are the sawed-off next generation of Americana music-makers. Their music respects the traditional aspects of the bluegrass and old-time music and envelops it with a punk-rock ethic. It's a country concoction you aren't likely to come across anywhere else. The six-man string band's latest effort, "Look Out," was released this summer. The boys from Hackensaw chop it with Hoots & Hellmouth and David Shultz and the Skyline at Toad's Place Thursday, Dec. 13, at 9 p.m. $5-$10. 648-TOAD.
