A converted church in rural central Pennsylvania has become a place where musicians with Amish roots are coming to record music and make videos that are drawing millions of views. Ragamuffin Hall in McCoysville was the setting last weekend for a concert by two of the rising stars in that burgeoning scene, the married couple Ben and Rose Stoltzfus. Ben and Rose performed along with the musician and producer behind Ragamuffin Hall, Conrad Fisher. Fisher describes most of what gets recorded at Ragamuffin Hall as “clean country music” and rootsy bluegrass, with a heavy dose of gospel.
