Since its beginning, Farm Aid has traveled the country, staging annual concerts and supporting local organizations working to strengthen family farms. Farm Aid builds the Good Food Movement by connecting people with family farmers who are increasing the supply of local, humanely raised, sustainable and organic food. This is the first time the annual benefit concert is being staged in the northeast.
