Brace yourself, southern Illinois -- the Prince of Darkness cometh. Ozzy Osbourne has signed on to headline Moonstock, a unique music festival set to coincide with a total solar eclipse. Southern Illinois has been determined as the spot that will have the longest duration of the rare total solar eclipse and festival organizers have invited Osbourne to "bark at the moon" with his set coinciding with the eclipse taking place.

Details are still coming together for the music weekend, but Osbourne has been confirmed to play on Monday, Aug. 21 at Walker's Bluff in Carterville, Ill., kicking off his show with "Bark at the Moon" at 1:20PM to coincide with the total solar eclipse. Moostock also lists Five Finger Death Punch performing on Sunday, Aug. 20, while headliners for Friday and Saturday (Aug. 18 and 19) have yet to be announced. More acts will be added to the music weekend as well.

Walker's Bluff is a picturesque winery hidden amongst the wooded environs of southern Illinois, and there will be camping options available for those attending Moonstock. To commemorate the occasion, Walker's Bluff have also begun selling their Ozzy Osbourne Solar Red wine, which can be found at this location.

Tickets for Moonstock will go on sale Tuesday, Feb. 21 at this location. For additional lineup and camping details, check the Moonstock website.
