Ralph Stanley is recovering from heart surgery in a hospital near his Southwestern Virginia home. The bluegrass legend underwent a five-hour triple-bypass procedure yesterday (June 27) that was described in a statement as uneventful.

The 78-year-old artist's doctors recommended the procedure after a routine checkup last week. He did not suffer a heart attack and as his heart is said to be strong, a "full and rapid" recovery is expected. "He got through the surgery with flying colors," Stanley's booking agent Keith Case tells Billboard.com.

Still an active artist, Stanley has a tour schedule that extends well into next year. Case says all of his July dates have been canceled, as well as some shows in early August. "He won't ever quit," Case says. "[At this point] we expect he'll get himself back out there sometime in August," with the itinerary to be re-evaluated in a few weeks.

One of the founding fathers of bluegrass, Stanley has been performing since the late 1940s in such acts as the Stanley Brothers with older brother Carter and the Clinch Mountain Boys.
