Edwin Huizinga, violin, and William Coulter, guitar, (Fire & Grace) return with special guest artists from their musical family, continuing their tradition of wildly popular, sold-out concerts with a program entitled “Pangea: One World.” This unique duo explores the connective musical elements of classical, folk, and contemporary traditions from around the world. Fire & Grace’s repertoire is vast, ranging from Bach to Vivaldi, tango to Celtic tunes, traditional Bulgarian to American fiddle tunes and waltzes, all played with a sense of discovery and commitment to the elements of passion and virtuosity — fire and grace — found in these diverse traditions.
