Since 2007, Pure Cane Sugar girls’ sultry voices, soulful harmonies, and powerful lyrics, have evoked exquisite vocals. The result is “an assemblage of masterful melodies and haunting harmonies that inspire sweet dreams”. With rooted accompanying artists Daryl Branford on drums, Jason “Junior” Tutwiler on slide guitar, and Bob Hart on bass, their original, artful arrangements are captured on a backdrop of textured synergy and rhythm. Make sure to get seats early at the South Stage at 8 p.m. Friday.
