Playing a pair of weekend shows in a music town is a big deal, so when the Charlottesville, VA-based Infamous Stringdusters roll into Athens for a couple of gigs at the Georgia Theatre, expect North Lumpkin Street to be the center of attention. Known for their long, intricate jams on instruments typically associated with bluegrass, the Stringdusters are well accustomed to showing off their virtuoso status. But the band's live show isn’t the only notable thing about it; the group has garnered a Best Country Instrumental Grammy nomination for its studio recording of "Magic No. 9." Local progressive-bluegrass torchbearers Packway Handle Band open up the Friday show, while the bluesy five-piece The Darnell Boys warm up the crowd Saturday.
