The California Bluegrass Association will celebrate its 50th annual Father’s Day Bluegrass Festival with a special 50th-anniversary lineup featuring headliners the Travelin’ McCourys, the Gibson Brothers and AJ Lee & Blue Summit, who top a 32-act roster packed with established and emerging talents coming together June 12-15 at the Nevada County Fairgrounds in Grass Valley, Calif.

The California Bluegrass Association’s 49th annual Father’s Day Bluegrass Festival is adding a pair of special shows to keep the music going after Friday and Saturday Main Stage performances, and has selected the Vern’s Stage lineup of afternoon performers. The festival also has slated a new youth activity: pre-school family jams.
