Live on the Legends Plaza Stage: Dirty Grass Soul! Proudly hailing from the musically rich foothills of Cleveland County (Shelby, NC), Dirty Grass Soul has been entertaining audiences across the Carolinas and beyond since their formation in 2011. With a sound that draws much influence from traditional music of the North Carolina foothills, Dirty Grass Soul manages to bring a new, refreshed, and re-energized sound to their music that falls somewhere between country, bluegrass, and southern rock & roll.
