For the 42nd time, a Christian rock festival will be held in a field near the central Kentucky community of Wilmore. Over the decades, much has changed at Ichthus and for fans who gather for music, lectures, workshops and fellowship. The first sounds of music will fill the air Wednesday. One of the nation's best known worship bands, ‘Hillsong United’ will help open the festival. Then on Saturday, the festival's final day, Ichthus Chief Executive Officer, Mark Vermillion says the focus will again be on community.
