The renegade traditionalists of Mipso are doing their part to take three-part harmony and Appalachian influences into new territory. Formed in Chapel Hill in 2010, these four North Carolinians are touring the country to support their latest release, “Dark Holler Pop." This band has wandered off the path blazed by Earl Scruggs and Doc Watson to find a new clearing for their Southern string band sound. In the process, they’ve kicked up a fuss. IndyWeek heralded the band’s role in the reemergence of Southern roots music in North Carolina, crediting Mipso with "expanding the vocabulary of common touchstones" for bluegrass. And all over the Southeast, Mipso has been busy playing raucously fun live shows that veer from up-tempo original melodies to madcap acoustic covers of Michael Jackson. The group puts all the energy of a college club show into a form of music that predates clubs. And most colleges.
