Bluegrass, or mountain music, was born in the hills of Appalachia in the early part of the 20th Century and gradually made its way into the pews of churches all throughout America. Along with gospel music, it has become a unique and treasured American art form. Now the legends of bluegrass music join voices and instruments with the best in gospel music for a remarkable three-part series hosted by Gospel Music Hall of Famer Bill Gaither and contemporary bluegrass banner-carrier, Marty Stuart.
