Nashville has been selected as the host city for the National Folk Festival in 2011, 2012 and 2013, organizers announced Wednesday (March 10). The event, the nation’s oldest and longest-running multi-ethnic traditional arts festival, is completing its three-year run in Butte, Mont., on July 9-11, 2010. In visiting Nashville, the festival will be celebrating its 75th anniversary in 2013. The free event, which is expected to attract 80,000 attendees in its first year in Nashville, is designed to provide the groundwork for a new festival that will continue locally when the festival moves to another city in 2014. Dates for the festival have not been announced.
