The concert is at 7:30PM at the Mitchell Performing Arts Amphitheater, Owosso, Michigan.
The concert is open to the public and there is no charge. It's paid for in part by a grant to the city of Owosso from the Michigan Council for Arts and Cultural Affairs. They will, however, be accepting donations. The amphitheater is located on the west side of Water Street, about 2 or 3 blocks north of the main street, highway M21.
