This young string quartet out of North Carolina is intent on keeping the tradition of African-American Americana music alive. The band occasionally reworks modern pop songs into their old-time stylings (their banjo-picking, fast-fiddling, beatboxing version of Blu Cantrell’s “Hit ‘Em Up Style,” sung by the fantastic Rhiannon Giddens, is particularly delightful) but mostly stick to playing revivalist blues, ragtime, early jazz, and roots to great acclaim—their 2010 album Genuine Negro Jig won a Grammy for Best Traditional Folk Album, and their original song “Daughter’s Lament” will appear on the much-ballyhooed T-Bone Burnett-produced Hunger Games soundtrack. With Shook Twins. ERIN K. THOMPSON
