Aspen is playing the barn stage 11am Sunday morning. The Earthwork Harvest Gathering is a celebration of food and music, featuring the freshest of local ingredients and fine imported specialties. As a family-friendly Gathering, the Earthwork Harvest Gathering has ripened Michigan's artisan culture, and hosts 2500+ attendees, who camp in the mixed hardwood forests and open meadows of Earthwork Farm every third weekend in September, annually.
