The 21 years since the birth of the Americana Music Association’s annual fall convention and festival have been rough on the American people but good for America’s music. It recalls the breakthroughs and beauty that came from the grassroots during the Great Depression. Hard times inspire art. As I traversed the city during my own 21st AmericanaFest, I saw a vibrant community, full showcases, exciting special events and optimism about the business.
