Filmed on location in seven different states during 1980-1981, America?s most loved and original music genre is the subject of ?That?s Bluegrass?. This care-free, fast-moving documentary lovingly examines our home-grown musical heritage from the simple front porch fiddler to famous Nashville recording stars. ?That?s Bluegrass? listens in as accomplished amateurs do some ?picking and grinning? at outdoor festivals and play songs handed down from generation to generation. Jimmy Martin recounts his growth from a simple southern farm boy to the energetic, toe-tapping ?bad boy of bluegrass.? The legendary Ralph Stanley describes how his religious upbringing in North Carolina formed the basis of his unique style loved by bluegrass fans everywhere. The highpoint of this colorful film presents the last filmed interview and performance of the beloved Lester Flatt of ?The Beverly Hillbillies? and ?Flatt and Scruggs? fame. His band?s performances of ?Foggy Mountain Breakdown? and ?The Ballad of Jed Clampett? are guaranteed to put a smile on your face and get your toes tapping.
