Graminy’s Chris Powers and Mike Bell will perform as a mandolin-guitar duo at Fermentation Fest, playing in the group’s distinctive “class-grass” style. The unwary should be warned: There may be banjo too. We’ll be on the Pasture Performance Stage, a few miles south of Reedsburg, WI at around 11:45am to around 1:15pm. (The Pasture Performance Stage will be on Pine Bluff Road, just north of the intersection with Short Cut Road. See the Fermentation Fest site for details.) Free admission!
