The Craft in America Study Center hosts a musical interlude with modern bluegrass group American Primitive.
From the Craft in America website:
Their playing is sharp and honed for the traditonal bluegrass taste with just the right touch of west coast grit. They have beautiful, blending four part harmonies that would bring a tear to ol' Bill Monroe's eye. These boys are the hottest pickers in California.
